Pro Tips for Getting the Best Results:

  • WCAG Accessibility: Aim for a minimum contrast ratio of 4.5:1 for body copy and 3:1 for large UI components to meet WCAG AA standards.
  • HSL for Consistency: When building tint and shade scales, adjusting lightness (L) in HSL often produces more natural variations than raw RGB manipulation.
  • Color Harmony: Pair dominant brand tones with complementary or triadic accents to guide user attention to key calls-to-action.
