Buttons tips

🔘

White text on the brand primary color must pass 4.5:1 for AA. Test before committing to a brand color — some popular colors (like bright yellow) fail with white text.

💡

Outline buttons need ≥3:1 contrast for the border AND for the text inside. Use the tool to test both.

🎯

For dual states (default + hover + active), test each state against the surrounding background separately.
