You can change the visualization color palette used in Workspace by choosing a different color palette or by specifying your own palette that could match your company’s branding colors. This feature affects most visualizations in Workspace, but it does not affect Summary Change, conditional formatting in Freeform tables, and the Map visualization.
Color palette support is not enabled for Internet Explorer 11.
Keep in mind:
Here is a video on using custom color palettes:
Navigate to Workspace > Project > Project Info & Settings.
From the Project Color Palette dropdown, you can pick one of five pre-set color schemes.
To specify your own palette, select Custom Palette below the pre-set options.
Specify up to 16 comma-separated hexadecimal values (for example, #00a4e4) for the colors you intend to use. If, for example, you want to use only four values, these colors will automatically be repeated in visualizations that contain more colors.
