The “Coolors Alt” slug identifies Gpick, a color picker and palette editor. Build a small palette from a real brand asset, adjust colors for contrast, and export values in the formats your design and code teams need. Reopen the palette and check that names and exact color values survive.
A palette tool is useful when it makes handoff consistent, not only when swatches look good. Test color sampling across displays and decide where approved tokens live so designers and developers use the same definitions.
