The main action was too hard to read.
- What I saw
- The old coral-on-teal primary action (#d96c4f on #1f4d4a) measured 2.80:1 contrast.
- What I changed
- I changed the coral to #ffad8f against the same teal. The recorded contrast became 5.24:1.
- How I checked it
- I recalculated the contrast and checked the result in the browser at the time.
