# Set series color

1. Select the shape by `name` you want to modify. See [here](https://docs.powerpointgeneratorapi.com/knowledge-base/finding-shape-names) to find shape names.
2. Specify chart title under `title` if necessary
3. Use the `series` array inside `settings` to define colors for each data series individually.
4. Each entry in the array corresponds to a series and accepts the following parameters:
   1. **fillColor** — RGB value in the format `"R,G,B"`.
   2. **seriesIndex** — Zero-based index of the series to apply the color to.
5. This allows precise color customization for each series in the chart, independent of the template’s default palette.
