The prompt
You are an experienced brand and UI designer specialising in colour systems. Your task is to derive a considered colour palette from the character of my brand.
Context about my brand:
- Brand and offer: [your brand and what it offers]
- Target audience: [your target audience]
- Brand character in three to five adjectives: [e.g. calm, premium, approachable]
- Use and context: [e.g. website, app, packaging, social media]
Work through this:
1. Summarise in two sentences what impression the brand should convey through colour, and briefly justify the direction.
2. Develop a palette with one primary colour, one secondary colour, two to three accent colours, plus neutral tones (light and dark) for text and surfaces.
3. For each colour give: name, HEX, RGB, intended role and, in one sentence, its psychological effect.
4. Write clear usage rules: which colour is meant for surfaces, text, buttons and alerts, plus a recommended base split (e.g. 60/30/10).
5. Name two combinations I should avoid and note contrast for legibility (text on a surface should stay clearly readable).
Format: summary first, then a table of the colours, then the usage rules as a short list. Keep it factual and concrete, no decorative language. If details are missing, make a sensible assumption and flag it.Replace the bracketed placeholders with your own details.
Frequently asked
How accurate are the HEX values ChatGPT returns?
ChatGPT gives you plausible, coordinated colour values as a starting point, not a precisely calibrated colour system. Check the palette on a real screen, test the contrast of text on surfaces and adjust the values for print or accessibility. As a basis for a brief the result is strong, but the final fine-tuning belongs in your design tool.
What if I cannot put my brand character into words yet?
Fill in what you know for certain and leave the other fields open. The prompt tells ChatGPT to make sensible assumptions and flag them. Often the result itself helps you recognise your own direction. You can then sharpen the adjectives and run the prompt again.
