## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability saylor-innovations-color-palette-generator-beaf29cb
```

Example prompt: Can you generate a full color palette for the hex color #3366FF, including all the harmonies like complementary, triadic, and analogous, plus the tonal scale and WCAG contrast ratios?

## When to prefer this

Choose this endpoint when you need a comprehensive, ready-to-use color palette derived from a single hex color, especially when you need WCAG accessibility data alongside design harmonies and a full tonal scale. It is ideal for design-system automation, brand color expansion, and accessibility auditing in a single call rather than stitching together multiple color-theory tools.

## Known failure modes

- Invalid or missing hex color parameter returns an error
- Malformed hex codes (e.g. wrong length, non-hex characters) may return a validation error or unexpected results
- Very short hex codes (1–2 characters) may not be interpretable
- Network or upstream service errors may result in HTTP 5xx responses

## How this service works

Color palette from a hex color - complementary, split, analogous, triadic and tetradic harmonies, a 50 to 950 scale, tints, shades and WCAG contrast ratios

## Output

Returns the input color normalized to hex, RGB channels (r, g, b 0–255), HSL values (hue in degrees, saturation and lightness in percent), a 50–950 tonal scale with tints and shades, color harmonies (complementary, split-complementary, analogous, triadic, tetradic), WCAG contrast ratios against black and white, and a recommended readable text color for overlay use.
