Scale
Turn one color into a Tailwind-style 50–950 scale. Steps are spaced evenly in perceived lightness (OKLCH), the hue stays put, and every step is checked as text on white and on black so you know which shades are safe before exporting.
Contrast per step
| Step | As text on white | As text on black |
|---|
WCAG ratios are symmetric, so "as text on white" also tells you how white text reads on that step as a background.
