# Monochrome palette

> Compose out-of-order monochrome steps for @servicetitan/anvil2-rn-charts-kit.

Themes assign monochrome color by series or datum index. Compose with `chartPalette` to reach a step outside that order.

* Design: [Look & feel](/docs/web/data-visualization/look-and-feel)
* Shared API: [Chart component](/docs/kits/charts-react-native/chart)

Select a step and apply it through `chartStepItemStyle`:

```tsx theme={null}
const steps = chartPalette(appearance, "monochrome");
// e.g. force the outlined pale step onto series 0, ignoring index order:
series: [
  {
    type: "bar",
    name: "Highlight",
    data: [1200],
    itemStyle: chartStepItemStyle(steps[3]),
  },
  // …
];
```
