The anatomy of a website palette

• Primary — your brand color, used for primary buttons and links.
• Accent — a secondary highlight for emphasis and hover states.
• Neutrals — a near-white background, a dark "ink" for text, and a mid-gray.

Turn a palette into CSS

Define your chosen colors as variables so they're easy to reuse and theme:

:root {
  --paper:   #EEF2FF;
  --brand:   #6366F1;
  --brand-2: #4338CA;
  --ink:     #111827;
}

Don't skip accessibility

Whatever palette you choose, make sure text meets the WCAG AA contrast ratio of 4.5:1 for body text. Accessible color is better UX — and better SEO.
