Theme Colours (from Settings) should be retired (now that we have custom gradient coloring). Make the primary theme color dynamically pulled from Workspace gradient's dominant color.

Basically what I mentioned in the title.

If you pick for example Purple for your Theme Colour, and your workspace is colored with a different color (eg. Green), it's so ugly.

Theme Colours can be just made obsolete, and let the browser take the dominant colour of the actual workspace's coloring.
