YES

As of 13 August 2026, AI can choose a colour palette for your website.

Most people should do this themselves; the prompt is on this page.

What the alternative costsFramer is an AI-assisted site design tool that publishes a production website, but no price comparison is supplied here.

If this goes wrong: the palette feels off-brand or fails on some content, so you revise it before publishing or replace it in the design system.

What to actually do

  1. Do it yourself

    The route this page recommends

    A chat interface, chat-fluent skill, and roughly 30 minutes until you can act on the result.

    How to actually do it

    1. Open a blank document and gather your existing logo colours, brand guidelines, website screenshots, competitor examples, target audience, website purpose and the types of content the site will contain.
    2. Paste those details into the prompt, replacing each bracketed slot with your information and writing none where a detail does not exist.
    3. Send the prompt to a chatbot and save the three palette directions, including every hex code, colour role and stated risk.
    4. Open a colour-contrast checker and test the proposed body text, heading text, links, buttons and focus states against each background; record any pair that fails and ask the chatbot for replacement hex codes.
    5. Apply the recommended palette to representative pages containing long text, forms, buttons, error messages, images and navigation, then compare it with your existing brand and competitor references.
    6. Ask a colleague who understands your audience to review the applied version without seeing the rationale, make the final selection, and update your design tokens or website styles before publishing.

    Prompt

    Choose a practical colour palette for this website.

Website or product: [describe it]
Audience: [describe the users, including any relevant UK context]
Purpose: [what visitors need to do]
Brand personality: [for example, calm, precise, energetic or trustworthy]
Existing brand colours or colours to keep: [list them, or write none]
Colours to avoid: [list them, or write none]
Competitors or visual references: [describe or paste links]
Website background and content types: [for example, long articles, forms, dashboards, ecommerce or photography]

Give me three distinct palette directions. For each one provide:
1. A short rationale tied to the audience and purpose.
2. Hex codes for the main brand, accent, background, surface, heading text, body text, border and success, warning and error states.
3. The intended role of every colour and where it should be used.
4. Light and dark surface options where they are useful.
5. Suggested button, link, hover and focus-state colours.
6. Any likely accessibility or readability risks.

Do not invent research, brand facts or competitor details. Do not describe a colour as accessible unless its contrast has been checked. Mark any contrast ratio as an estimate and tell me which foreground and background pair it refers to. End by recommending one direction and list the specific decisions I still need to make before publishing.

    Open it prefilled in ChatGPT or Claude, or copy it into Gemini, which takes no prefill link.

  2. Use a tool built for this

    Second choice

  3. Hand it to a person

    The distant third

    A person who owns the outcome does this end to end, worth it when the failure is dear.

What it gets wrong

Even on a YES, the friction has a name: taste and context depth.

FAQ

Can ChatGPT choose a colour palette for my website?
Yes. It can generate several palette directions, hex codes, colour roles and suggestions for buttons, links and page surfaces. You still need to apply the palette, check contrast and decide whether it fits your brand and audience.
What colours should I use for my website?
There is no reliable universal palette because the right choice depends on your audience, purpose, brand and content. Give AI those details and ask for several options, then test the chosen colours on real pages rather than selecting from the hex codes alone.
Can AI make sure my website colours are accessible?
AI can identify likely contrast problems and suggest colour pairs, but you should verify them with a contrast checker and test the actual interface. Check body text, headings, links, buttons, focus states and error messages separately.
Is it free to use AI to choose website colours?
A free chat interface is enough to generate and document palette options for this task. A design tool can help apply the palette to a working site, but the supplied tool information does not provide a price comparison.
