What Are Color Models?
Color models are mathematical systems for representing colors as numbers. HEX codes like #FF5733 are shorthand for RGB values used in web development. RGB (Red, Green, Blue) defines colors by mixing light, with each channel ranging from 0 to 255, producing over 16 million possible combinations.
HSL (Hue, Saturation, Lightness) takes a more intuitive approach by separating color identity from brightness and vividness. Designers often prefer HSL because adjusting lightness or saturation is straightforward without affecting the base hue. Understanding these models lets you convert between formats, maintain brand consistency across platforms, and make accessible color choices for all users.

Color Selection Tips
Use HSL for Quick Adjustments
Need a lighter variant? Increase the L value. Want a muted tone? Lower S. HSL makes systematic variations effortless.
Follow the 60-30-10 Rule
Use your primary color for 60% of the design, secondary for 30%, and an accent for 10% to create visual balance.
Meet WCAG Contrast Standards
Normal text needs at least 4.5:1 contrast against its background. Large text (18px+ bold) requires a minimum of 3:1.
Leverage Complementary Harmony
Colors opposite on the color wheel create strong contrast. Use them for call-to-action buttons against neutral backgrounds.
Test in Dark and Light Modes
A color that looks great on white may wash out on dark backgrounds. Always verify your palette in both themes.
