# Customizing the appearance of your project

To customize the colours used by default in your organization, head to the `Organization settings` --> `Appearance` and you can update any and all of your default colours used in your organization.

## Update the default colours used in charts

You will see a list of colour palettes that you can choose from.

## Use the palette in a chart

The next time you build a chart, it will default to using these colours for the series, unless you override them in the chart config.
