Advanced Color Palette App Maker

Builds a colour palette studio you open by double-clicking. Not another gallery to scroll. Build a palette, expand any colour into a nine-step ramp, copy hex, RGB, HSL or OKLCH in one click. Then check it: a grid scoring every pair for WCAG contrast, and a switch that redraws it all as someone colour blind sees it. Export as CSS, Tailwind, SCSS, JSON, or a labelled PNG with your logo. Locked graphite dark theme, one gold accent, light mode, full three-column workspace.
