Frequently Asked Questions about Color Palette Generator

Which shade steps on a 50–950 scale are safe for accessible body text?

On light backgrounds (`white` or `50`), shades `700`, `800`, `900`, and `950` consistently pass WCAG AA (`4.5:1`) contrast. Shades `400` and `500` should be reserved for borders, icons, or large headings (`≥18pt`).

Why does linearly stepping HSL lightness create muddy dark shades and washed-out pastels?

Pure linear HSL lightness interpolation loses chroma saturation near the extremes. Adjusting saturation along a parabolic curve (or interpolating in OKLCH space) keeps `100–200` tints crisp and `800–900` darks rich.

How do I use the exported CSS variables in Tailwind CSS v4?

Place the exported `--color-primary-50` through `--color-primary-950` tokens inside an `@theme { ... }` block in your main CSS file, and Tailwind v4 will automatically generate `bg-primary-500`, `text-primary-700`, and `border-primary-200` utilities.

Why should pure complementary colors (`180°`) not be used for text on background?

Placing a high-chroma complementary text color directly on its opposite hue at similar luminance causes chromostereopsis (visual edge vibration). Always separate them by at least `50%` lightness.
