Brand palettes with hex codes — 100% free, runs in your browser
Palettes built on colour theory hold together better than colours picked one at a time. Complementary schemes create contrast, analogous ones feel calm, and shades of a single colour are the safest starting point for a brand.
Shades and tints for a calm, cohesive brand. Complementary when you need a colour that demands attention, such as a call to action.
One primary, one accent, and a few neutrals. More than that becomes hard to apply consistently.
