WTH [Energy Dashboard] - Ability to change color of each entity in Graphs

It would be nice to be able to change the colors for each entity being tracked in the energy dashboard.
As an example, I have 3 tariffs for energy, and they have very similar blue colors. I would like to be able to distinguish them better.

I also use the Gas graph to track water usage (as it’s m3 as well), and would like to have that entity as blue.

Yes! I totally agree. One would think this should be relatively easy??? I am curious as to where the 'default colors ’ are defined in HA.
