# Variable: colorAdjustTool

```ts
const colorAdjustTool: Tool<SpooledArtifact>;
```

Defined in: [batteries/tools/color/index.ts:629](https://github.com/NHTIO/ADK/blob/v1.20260605.0/src/batteries/tools/color/index.ts#L629)

Lighten or darken a colour by a percentage of HSL lightness.

## Remarks

`amount` is clamped to `[1, 100]`; `steps` is clamped to `[1, 10]`. With `steps > 1` the tool
emits a ramp of progressively-adjusted colours, useful for generating tint/shade scales.
