Use these colors for all components: Background: #EEF0F1 Text: #1C2E3B Accent: #81909B Support: #C08D68 Neutral: #C1C3D1 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
