Rainbow color palettes

Rainbow palettes pair the spectrum with white or black structure so every hue stays distinct.

Rainbow palettes borrow their logic from a familiar reference, which gives your work instant recognition. Every scheme on this page keeps that reference clear while staying usable in real layouts.

A strong example from this page is Full spectrum: #30e3e8, #3c30e8, #e830d7, #e84830, #cae830. It works immediately for layouts, and you can open it in the generator to get RGB, HSL, CMYK, and Pantone values.
