Guide to Web Color Spaces & Formats

Understanding sRGB, HSL perceptual cylindrical models, and digital contrast requirements.

sRGB vs HSL

sRGB defines colors through red, green, and blue light channels (0 to 255). HSL re-maps this into Hue (0° to 360° angle on the color wheel), Saturation (chroma intensity), and Lightness (perceived illumination), making programmatically dynamic themes and palettes far easier to construct.

WCAG Accessibility Standards

WCAG 2.1 Level AA requires a minimum contrast ratio of 4.5:1 for normal body text and 3:1 for large text (18pt+). Checking your brand colors against both white and black backgrounds prevents inaccessible low-contrast interfaces.
