It's common feedback that users want to have a different set of colors for their charts. We should add an option to customize the color theme. The option will be a global one (and not per user).

If we don't need the color names, then implementing this can be as simple as providing an input box for comma separated list of color hex values in the organization settings page.

It would also be useful to include the ability to adjust the transparency / alpha of the color as well. This is particularly useful on busy plots, such as a scatter or a map

As a general thought, decent looking custom palettes can be programmatically generated (eg use HSV instead of RGB, and distribute values):

Alternatively, Cynthia Brewer's "Color Brewer" can be used to generated good palettes manually:
