Color Palettes

Introduction

Color palettes let you define a consistent set of colors for your charts, so every visualization in your workspace follows the same brand or style. In Holistics, palettes are defined as code and can be applied to individual charts, set as the project-wide default, or referenced in a dashboard theme for organization-wide consistency.

How-to

Create a color palette

To create a palette, go to Development > Library > Palettes and create a new .palette.aml file:

ColorPalette palette_name {
  title: "Display Name"       // shown in the palette picker
  categorical {
    colors: [
      "#FF5733",                // accepts hex, rgb, oklch, and other CSS color formats
      "#33FF57",
      "#3357FF"
    ]
  }
}

See ColorPalette AML reference for all available parameters.

Apply a color palette

Once defined, select the palette in the Visualization Settings of any chart in the Edit or Explore modal.

To apply a palette across all charts in a dashboard at once, reference it in a dashboard theme.

Set the global default palette

You can set the global default palette for all charts in your project in two ways:

• GUI: Go to Project settings > Dashboard & Visualization > Default color palette and select from the dropdown.

  

• Code: Update the settings.aml file in your Development > settings folder:

  ProjectSettings project_settings {
    viz {
      default_color_palette: palette_name
    }
  }

Legacy palettes

These palettes were created through the old Admin Settings before as-code palette support was introduced. They have a few limitations - have no AML definition, and cannot be referenced in a dashboard theme.

You can find legacy palettes under Project Settings in Development alongside your as-code palettes. You can view, use, and delete them, but you cannot edit them or set them as default. To replace a legacy palette, delete it and recreate it as a .palette.aml file.

FAQs

Will changing the default color palette affect existing charts using the previous default scheme?

Yes. If the default color palette is changed, existing charts using the default setting will be updated to use the new default color palette.

Can I delete the default color palette?

You cannot delete the default color palette unless you have set another palette as your default option.
