How it works

All processing happens locally, in your browser. No color is ever sent to a server. RGB describes a color by how much red, green, and blue it has (0 to 255 each). HSL describes the same color in a way that's more intuitive for visual tweaks: hue (the color itself, 0 to 360°), saturation (intensity, 0 to 100%), and lightness (how light or dark, 0 to 100%).
