Ramps

Every shade you will need.

Eleven steps per colour, from 50 (almost white) to 950 (almost black). The hue is held in OKLCH; where a step cannot hold the colour's full strength on screen, it is softened, never shifted. The ring marks the step nearest your own colour.

Ramps are a starting point, not a rule: check text-on-background pairs from your ramps in the contrast grid before you use them. Screens differ, and printed colour differs from screen colour. RiotPad works in screen colour (sRGB); it does not match paint, ink or fabric colours.
