Contrast

Check color contrast without leaving your kit

Test any pairing for readable, accessible contrast before it reaches a screen reader or a squinting user. It's built into the same place your colors already live.

How it works

  • Pick two colors — a foreground and a background from your collection.
  • Read the WCAG-style result Pocket CVI calculates for the pair.
  • Adjust and recheck until the combination clears the bar.
  • Keep the winners in the brand kit so the whole team uses accessible pairings.

Why it matters

Contrast failures are the most common accessibility miss, and they're the easiest to catch early. Checking a pairing while you're still choosing colors is far cheaper than patching it after launch.

Where it fits

Because the checker lives next to your palette, there's no copy-pasting hex codes into a separate web tool. Validate text-on-background choices as you build the kit, so accessibility is baked into the brand rather than bolted on.

FAQ

What standard does the checker use?

It runs WCAG-style contrast checking, the same approach used for web accessibility, so you can judge whether a pairing is readable.

Do I need a separate accessibility tool?

No. The contrast check is built into Pocket CVI right beside your colors, so you test pairings without leaving your brand kit.
