Every icon size a site needs, plus the markup.

A palette is a decision about legibility as much as taste. A brand colour that cannot carry text on white is a constraint you want to discover before the design, not after the accessibility audit.

So every colour here comes with its contrast ratios. Not a vague "passes" badge, the actual numbers against white and black, calculated the way the accessibility guidelines define them.

Questions

What do the contrast numbers mean?

They are ratios. 4.5 or more passes AA for normal text, 3.0 passes AA for large text and interface borders, 7.0 passes AAA for normal text.

Are my images uploaded?

No. They are decoded and analysed in your browser.

Why do results differ from other palette tools?

Palette extraction is an approximation. Clustering averages similar pixels, so algorithms disagree, and none of them is wrong.
