Handling the color schemes in insights could be improved in various ways, the main aspects being:
1. Allow users/administrators to save color palettes (especially useful for corporate designs, etc.)
2. Allow users to customize colors in legends more freely, e.g, when working with color ranges (some predefined color palettes are not useful as they are either white in the middle or non-ergonomic, e.g. for people with red-green visual impairments)
