As Scrummaster I would like to choose from more colors for epics

The colors you can pick from are really sort of restricted.
We are currently using 20+ Epics and there are only 8 colors to choose from. until now it was possible to manually alter the color code but with the latest release the color field is not configurable anymore. please give us a color to open up the whole color palette (or at least 128 or 256 colors )

also, the new selection-color (light-grey?) when selecting an epic in the epics panel is so light that you hardly see what epis is selected. please revert back to green or something else that springs to the eye a bit better
