When I setup custom colors with info i got from:
As I followed those instructions, on the cubase Project Colors Setup tab and clicked on the Store Color Set as Default button - I also believed the button did not work, as you are saying. I found out that it is actually working! You see the thing is that the button does not “appear” to work because the buttons screen graphics do not change when it is clicked, to give the user feedback to let the user know that it worked - However Cubase has in fact stored the color set - same deal with the reset button. It is a bug, because it should “appear” to click to provide the user feed back, but the easy work around is to simply understand that it actually does save the color set. Give it a try for yourself.
