Trying to understand a color feature!

What exactly does this do? I don’t see any color changes to the site after applying one. Also when it comes to working with 2 or more companies, in version 4 it was nice that we could easily differentiate what company we were working on due to the header color of the app. Example company 1 = blue company 2 = red. Does Version 5 have this feature also?

In v4 the color affects the company invoice and client portal but does not affect the app.

In v5 the color affects the company app accent color (and will eventually be used for the light theme header).

Its hard to tell, I have 2 companies with different colors and i can’t see any difference.
