Crimson, Sea Green and Cream lead the list. Each partner is a real named colour with the reason it works — a wheel relationship, a neutral that carries it, or a pairing lifted from a palette or brand system that actually shipped — and every pair opens in the palette tool.

Sea Green #2e8b57

Cream #fffdd0
