Changing item icon background colors?

[MacDaddy62]

I don't like the gray background that Profit uses for item icons in the inventory. I'd like to switch it to the standard blue, but I can't figure out where this variable is located in any of the UI files. Can anyone tell me where it is? Thanks.

Nevermind, figured it out. One of profit's extra files sets those colors.
