Use these colors for all components: Background: #F1F3F4 Text: #1A2C32 Accent: #289EC4 Support: #B97E6A Neutral: #C4C9D9 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
