Trying to get my head around creating and personalizing one.
Can someone tell me where i would look to change the Button colors and text color etc.
Here is an example of my current problem.

Obviously its too dark and i need to change it to be more readable.
Thanks if anyone can help.

Type in control in the search box for the stylevars and all/most of those control those buttons
