Using the palette

In Recolor the order of the colors is meaning: swatch 1 takes the page's heaviest brand color, swatch 2 the next, and the page's greys take a tint of swatch 1 (how that works is in mapping). Reorder the swatches and the page reorders with them. To keep text readable, the table above says whether black or white text reaches the WCAG AA ratio of 4.5:1 on each color; #001f2b is the darkest of the five.

The code below is what Recolor's own Export panel writes for this palette. The Tailwind block is a Tailwind v4 @theme block, and the Coolors link opens the same colors there. To see the palette on your own site first, follow previewing a palette on a real website.
