In brief: A repeatable method for building a palette from a reference image, mood, or project requirement. This guide explains the core idea, practical ways to apply it, and common considerations to check before making a final choice.

Define the purpose

A palette for a website, bedroom, outfit, or brand has different practical constraints. Identify where the colours will appear, what needs to stand out, and which colours must remain readable or printable.

Choose a starting point

Begin with a reference image, material, existing brand colour, or mood. Extract a few candidate colours, but do not use every colour from the source. Select the hues that support the purpose of the project.

Create roles and hierarchy

Assign each colour a role such as background, surface, primary, secondary, accent, or text. A palette becomes easier to apply when its roles are defined rather than left to individual judgement on every page.

Test and refine

Check the palette in realistic mock-ups. Review contrast, neighbouring colours, large and small areas, and different devices or materials. Remove colours that do not have a clear purpose.

Frequently asked questions

How do I start a colour palette?

Start with the project's purpose and one useful reference colour or image, then build supporting colours around it.

Should every colour in a palette be used equally?

No. Defining dominant, supporting, and accent roles creates clearer hierarchy.

How many colours are ideal?

The right number depends on the project. A small, well-defined palette is often easier to manage than a large set of unrelated colours.
