Use these colors for all components: Background: #EBEEEF Text: #16272C Accent: #33748A Support: #9E5942 Neutral: #C3C7D5 Rules: - Use Background for surfaces and canvas - Use Ink for body text and icons - Never use Accent as body text — contrast is too low - Maintain 4.5:1 minimum contrast for normal text
