Can I make this theme of white?

This review is for a previous version of the add-on (1.2.1). 

Most theme colors are controlled by Operating System

Most of Classic Compact's colors are controlled by the operating system. So, in theory, you should be able to make Classic Compact white by changing your system colors (e.g. display properties in Windows).
