Website Terms of Use

The agreement between you and Jumi Ltd covering your use of the JUMI Colour Generator.

1. Introduction

Welcome to the JUMI Colour Generator. These Terms of Use ("Terms") are a legal agreement between you and Jumi Ltd, a company registered in England and Wales (company number 17185825) with its registered office at 3 Trafalgar Court, Farnham, England, GU9 7QE ("Jumi", "we", "us").

By using jumicolourgenerator.com (the "Service") you agree to these Terms. If you do not agree, please do not use the Service. There is no account or sign-up, so these Terms apply from the moment you use the site.

If you are using the Service on behalf of a business, you confirm you have authority to bind that business, and "you" includes it.

Our Privacy Notice, Cookie Policy, Copyright Policy and Affiliate & Advertising Disclosure form part of how we run the Service and are worth reading alongside these Terms.

2. Definitions

3. The Service

The JUMI Colour Generator is a free, browser-based tool for creating colour palettes and CSS gradients, checking colour contrast against WCAG thresholds, and exporting the result in developer-ready formats.

Three characteristics of the Service shape everything in these Terms:

• It is free. We charge nothing. The Service is funded by advertising and affiliate links (see Section 10).
• It has no accounts. You do not register, and we hold no profile of you.
• It runs on your device. Your palettes, gradients and saved work are generated and stored in your browser, not on our servers. We never receive them.

4. Your licence to use the Service

We grant you a personal, non-exclusive, non-transferable, revocable licence to use the Service for creating Output, in accordance with these Terms. This licence covers use by individuals and businesses alike.

You may not sub-license the Service, offer it to others as your own product, or use it to build a competing colour or gradient tool. Section 11 covers our underlying software and content.

5. Output you create

Your Output is yours to use. You may use the palettes, gradients and exports you create with the Service for any lawful purpose, personal or commercial, without watermark, credit or fee. That includes using them in client work, in commercial products and in software you sell.

Colours themselves are not owned. Individual colours and their hexadecimal, RGB or HSL values are not, in general, capable of copyright protection under the law of England and Wales, and we make no claim of ownership over any colour value the Service produces or displays. Nothing in these Terms is intended to give either of us proprietary rights in a colour.

One boundary. The Curated Palettes are a compilation we have selected and arranged, and the compilation itself, together with its names and descriptions, is ours (see Section 7). Using a Curated Palette in your own design is exactly what it is there for; republishing our collection as a competing palette library is not.

Your responsibility. You are responsible for how you use your Output. In particular, a colour or colour combination may be protected in a specific commercial context by trade mark law, registered design rights or passing off — for example, a colour strongly associated with an established brand in your sector. Checking that your use is clear of third-party rights is your responsibility, not ours. We do not provide legal advice.

6. Accuracy and checking your results

We take care to make the Service accurate, and its contrast calculations follow the relative-luminance formula published in the Web Content Accessibility Guidelines (WCAG) 2.1. Even so:

• contrast figures are a mathematical guide, not a certificate of compliance — real-world legibility also depends on typeface, weight, size, rendering and the device in front of your reader;
• screen colour varies between displays, and colour on screen does not reliably predict colour in print, where you should work from a proofed physical sample and the correct colour profile;
• exported code should be tested in your own build before you rely on it in production.

You remain responsible for checking your Output against the accessibility, brand and production standards that apply to your project.

7. Curated Palettes and Site Content

The Service includes a browsable collection of Curated Palettes, together with guides, articles and examples.

7.1 What you may do

We grant you a worldwide, royalty-free, non-exclusive licence to use any Curated Palette — its colours, in any combination — in your own designs, for any lawful purpose, personal or commercial. You do not need to credit us, and this licence continues for work you have already produced even if you stop using the Service.

7.2 What you may not do

You may not:

• copy or scrape the Curated Palette collection, in whole or in substantial part, to publish it as your own palette library, dataset or product;
• reproduce our guides, articles, example content or other Site Content on another site, in whole or in substantial part, without written permission;
• use the Service or the Site Content to train machine-learning models, or to build a competing colour or gradient tool;
• present the Service, or Output produced by it, in a way that suggests Jumi endorses your product or organisation.

The test is simple: the colours are yours to use; our collection, our writing and our software are not yours to republish.

7.3 What we promise about the Curated Palettes

We have selected and arranged the Curated Palettes ourselves and we are not aware of any third-party claims over them. Because a palette is a set of colour values, the scope for third-party rights is narrow — but we do not give an unlimited warranty of non-infringement, particularly as to the use you put a palette to in your own market. If you become aware of a claim relating to a Curated Palette or any Site Content, tell us at legal@jumi.uk; we will investigate and will remove or replace material that is the subject of a substantiated claim. Our Copyright Policy explains how anyone can raise a concern.

8. Acceptable use

You may use the Service only for lawful purposes. This Section applies in spirit as well as to the letter.

8.1 Content standards

You must not use the Service to create or distribute material that:

• infringes anyone's copyright, database right, trade mark or other rights;
• is unlawful or fraudulent, under the law of England and Wales or of the country you are using the Service from, or promotes or assists unlawful activity;
• is child sexual abuse material, or otherwise sexualises, exploits or harms (or attempts to harm) children;
• constitutes hate speech, promotes violence or terrorism, or promotes discrimination based on race, sex, religion, nationality, disability, sexual orientation or age;
• is defamatory, obscene, threatening, or intended to bully, harass, intimidate or humiliate any person;
• is deliberately deceptive, including impersonating or misrepresenting an affiliation with any person or brand, or reproducing the get-up or brand colours of another business in order to pass your goods or services off as theirs;
• breaches a legal duty you owe to someone else, such as a duty of confidence or a contractual restriction.

8.2 Prohibited conduct

You must not:

• knowingly introduce viruses, trojans, worms, logic bombs, spyware or any other malicious or technologically harmful code;
• access without authority, interfere with, damage or disrupt the Service, our servers or networks, any software used in providing the Service, or any equipment, network or software belonging to a third party;
• scrape, crawl or bulk-download the Service, the Curated Palettes or the Site Content, by any means including automated tools;
• reverse engineer, decompile or copy the Service's software except as permitted by law, or reproduce, duplicate or re-sell any part of the Service;
• circumvent, hide or block the advertising that funds the Service, where doing so breaches these Terms' spirit of fair use of a free tool (using a standard browser with standard settings is fine);
• resell access to the Service or wrap it in another product.

8.3 How we enforce this Section

Because the Service runs on your device and we do not see what you create, we rely on this Section rather than on moderation. We will decide, acting reasonably, whether this Section has been breached.

Breach of this Section is a material breach of these Terms. Where we consider a breach has occurred we may take any action we reasonably think appropriate, including: issuing a warning; withdrawing or restricting your right to use the Service, immediately, temporarily or permanently, including by technical means; bringing legal proceedings, including to recover reasonable costs resulting from the breach; and disclosing information to law enforcement authorities where we reasonably consider it necessary or are required by law to do so (in practice we hold very little information about users; see our Privacy Notice).

We are not responsible for loss arising from action we reasonably take in response to a breach of this Section. This does not limit Section 13 or your statutory rights.

9. Saving your work

The Service saves the palettes and gradients you choose to save into your browser's local storage. This means:

• your saved work lives only on that device and browser, and does not sync anywhere;
• clearing browser data, using private browsing, or switching devices means your saved work will not be there;
• we cannot recover lost work, ever, because we never had it.

Copy or download anything you care about. This is the single most important practical point in these Terms, which is why it has its own section.

10. Advertising and affiliate links

The Service is funded by advertising (served through Google AdSense) and by affiliate links, where we may earn a commission on purchases you make from partners at no extra cost to you.

• Ads are served according to the choices you make in our cookie banner; see the Cookie Policy.
• Affiliate relationships are disclosed in our Affiliate & Advertising Disclosure.

Advertisers and affiliate partners are separate businesses. We are not a party to any purchase you make from them, and their products and sites are their responsibility, governed by their own terms. This does not affect your statutory rights against those businesses.

11. Our intellectual property

The Service, including its software, design, branding, guides, articles and the Curated Palette collection, is owned by or licensed to Jumi Ltd and protected by intellectual property laws. Except for the licences expressly granted in Sections 4, 5 and 7, we reserve all rights. "JUMI" and associated logos are our trade marks; do not use them without written permission, except to truthfully state that a palette or gradient was made with the JUMI Colour Generator (which we encourage).

12. Third-party trade marks

This Service references third-party products by name solely to describe compatibility or interoperability features — for example, a button that formats gradient CSS in a structure suited to YOOtheme Pro's custom CSS fields, or an export that matches the shape of a Tailwind CSS colour configuration. Such references are nominative and do not imply any affiliation, sponsorship, partnership or endorsement between Jumi Ltd and the trade mark owner, unless expressly stated.

"YOOtheme" is a trade mark of YOOtheme GmbH. "Tailwind CSS" is a trade mark of Tailwind Labs Inc. Any other third-party names, logos or trade marks mentioned on this site belong to their respective owners. Jumi Ltd is not affiliated with, sponsored by or endorsed by any of them.

13. Disclaimers

The Service is provided free of charge and "as available".

• We do not guarantee the Service will be uninterrupted, error-free or always available, or that any particular feature will remain available.
• We do not guarantee that Output will be fit for any particular production process. Test exported code in your own build, and proof colours physically before committing to a print run.
• Contrast results are a guide to WCAG conformance, not a certification of it, and we do not warrant that a design using our Output complies with the Equality Act 2010, the Public Sector Bodies Accessibility Regulations 2018 or any other accessibility requirement that applies to you.
• We do not provide legal advice. Whether a particular colour or palette can lawfully be used in your specific circumstances (for example, trade mark clearance for commercial branding) is your responsibility.

Nothing in this Section limits the promises we do make in Section 7.3, and nothing in these Terms affects your statutory rights as a consumer. Under the Consumer Rights Act 2015, digital content must be as described, and services must be performed with reasonable care and skill; these Terms do not exclude that.

14. Our liability

What we never limit. Nothing in these Terms excludes or limits our liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, or for anything else that cannot be excluded or limited under the law of England and Wales.

If you are a consumer. We are responsible for foreseeable loss or damage we cause by breaching these Terms or by failing to use reasonable care and skill. We are not responsible for loss that was not foreseeable, loss caused by events outside our reasonable control, or loss connected to business use (see below). Remember that we cannot be responsible for loss of palettes saved in your browser, because that data never reaches us and its safekeeping is necessarily in your hands (Section 9).

If you use the Service for business. To the fullest extent permitted by law, we exclude liability for loss of profits, revenue, business, goodwill, anticipated savings, and for indirect or consequential loss — including the cost of reprinting, rebuilding or reworking any design, campaign or product that used Output from the Service. Our total aggregate liability to a business user arising out of or in connection with the Service is limited to £100. This reflects that the Service is provided free of charge; a free tool cannot sensibly carry the liability profile of a paid one.

Your responsibility to us. If you use the Service in breach of Section 7.2 or Section 8 and we face a third-party claim as a result, you will compensate us for losses and costs reasonably arising from that claim. This paragraph applies to business users only.

15. Changes to the Service and these Terms

The Service. We may change, suspend or withdraw the Service, or any feature of it, at any time. Because the Service is free, we may do this without liability, although we will give reasonable notice on the site of any planned withdrawal so users can export saved work.

These Terms. We may update these Terms from time to time, for example to reflect new features, legal requirements or changes to our business model. The current version, with its version number and effective date, will always be at this page. Material changes will be flagged by a notice on the site. Your continued use of the Service after a change takes effect is acceptance of the updated Terms; if you do not agree, stop using the Service.

16. General

Entire agreement. These Terms and the documents referred to in them are the whole agreement between you and us regarding the Service.

Severability. If any provision is found unenforceable, the rest remain in force.

No waiver. A failure by us to enforce a provision is not a waiver of it.

Assignment. We may transfer our rights and obligations under these Terms to another organisation (for example, on a sale of our business); we will tell you on the site if this happens. You may not transfer yours, although your licences under Section 7.1 travel with the designs you have already produced.

Third parties. These Terms do not give rights to anyone other than you and us, and the Contracts (Rights of Third Parties) Act 1999 does not apply.

17. Governing law and disputes

These Terms are governed by the law of England and Wales, and the courts of England and Wales have jurisdiction over any dispute. If you are a consumer living in Scotland or Northern Ireland, you may also bring proceedings in your local courts, and you keep the benefit of any mandatory consumer protections of the country you live in.

If something goes wrong, contact us first at hello@jumi.uk. Most issues can be resolved without any of the above.
