How to use the palette

Start with your main brand colour. Use the darker and lighter shades for backgrounds and text, and the contrasting accent sparingly — for buttons and highlights, where you want the eye to go. Check contrast for readability (dark text on light backgrounds, or vice versa). A tight palette of a few colours looks more professional than a rainbow.

Frequently asked questions

How many colours should a brand palette have?

Usually one primary, one or two accents, plus neutrals (light and dark). Fewer, used consistently, looks more polished than many colours.

What are hex codes?

Six-character codes like #3b82f6 that specify an exact colour for web and design tools. Copy them straight into your CSS or design app.

How do I turn a palette into ads?

Apply it to your creatives manually, or use a tool like AdCreative.ai that generates on-brand, conversion-focused ad designs for you.
