UI Design tips
Common UI accessibility fail: status indicators in red/green only (errors red, success green). For deuteranopes, these look similar.
Always pair color with a non-color cue: icons (✓/✗), bold text, borders, or words ("Error", "OK").
Test your app's key screens in deuteranomaly mode — the most common form (~5% of men). If your UI breaks here, it fails for millions of users.
