Color Theory and Palette Design

Color theory, the difference between HEX, RGB, and HSL, and professional color palette design explained.

Color Model Basics

There are multiple ways to represent colors in computers. HEX (#FF5733), RGB (255, 87, 51), and HSL (Hue/Saturation/Lightness) all represent the same color differently. Web design mainly uses HEX and RGB, while HSL is more intuitive for animations and color generators.

Color Theory Fundamentals

  • Complementary: Opposite colors on the wheel. High contrast, attention-grabbing
  • Analogous: Adjacent colors. Natural and harmonious impression
  • Triadic: 3 equidistant colors. Balanced with variety
  • Monochromatic: Shades of one color. Elegant and minimal

Accessibility and Color Contrast

WCAG 2.1 accessibility standards require a minimum contrast ratio of 4.5:1 (AA standard) between text and background. About 8% of the population has color vision deficiency. Never convey information through color alone — always combine with icons or patterns.

Professional Color Palette Design

Excellent UI design requires a consistent color system. The foundation is one primary color, 1-2 secondary colors, neutral colors (grayscale), and semantic colors for error, success, and warning states.

Popular Color Palette Examples

  • Material Design: By Google. Simple primary + accent color structure
  • IBM Carbon: Enterprise-focused. Strict system emphasizing accessibility
  • Open Color: Open source. Vibrant and uniform color families
