Add variants colors of GUI

Some people don’t like the red theme of CIS v4.
Can to do several standard colors of GUI.
I think that it not be too difficult.
Example: red, blue etc.


If making CIS4 themes is like making CIS3 themes, I may just make my own grayscale theme at some point. So I’m not making any promises but if I do get around to it, I’ll make sure to post whatever I come up with.


I’m definitely not a fan of the red theme.
