Brilliant UI: Spectrum

Most color tools give you a ramp. Spectrum gives you a system. Built around the principle that great UI design relies on depth — many harmonious shades of the same color — Spectrum generates mathematically derived shade spectrums with intentional density at the light and dark extremes. Your neutral palette is derived from your primary brand color, not generic gray. Output includes full Figma Variables for both primitives and semantic tokens (success, warning, danger, info), ready to drop into any project.
