The Math Behind Beautiful Color Palettes

Every time you pick colors for a project by eyeballing it, you're ignoring geometry that would give you better results in less time. Color harmony isn't subjective. It's angular relationships on a wheel, and once you understand the math, you stop guessing. Complementary colors sit 180 degrees apart. Analogous colors are within 30 degrees. Triadic colors form an equilateral triangle at 120-degree intervals. These aren't aesthetic opinions. They're spatial relationships in the HSL color model that consistently produce palettes that work. HSL: The Color Model That Makes Sense RGB is how screens render color. HSL is how humans think about it. Hue is the angle on the color wheel (0 to 360 degrees), saturation is the intensity (0% to 100%), and lightness controls how bright or dark the color appears (0% is black, 100% is white, 50% is the pure color). When you work in HSL, generating color schemes becomes arithmetic. Red is 0 degrees. Orange is around 30. Yellow is 60. Green sits at 120, cya
