}About Color Harmony Generator
Color harmony is a principle of color theory that produces visually pleasing combinations. Complementary colors sit opposite each other on the color wheel (180°) — high contrast, bold impact. Analogous colors are neighbors (±30°) for a cohesive, natural feel. Split-complementary uses two colors flanking the complement (±150°/±210°) for contrast with less tension. Triadic spaces three hues 120° apart for a vibrant, balanced look. Tetradic and square schemes use four hues at 90° intervals for maximum variety. Monochromatic varies lightness at a fixed hue for an elegant, unified theme. Copy any swatch hex or grab the generated CSS custom properties to drop straight into your stylesheet.
