Does anybody know how to set the wine colors so programs fit in with the KDE4 color scheme as best as possible? Basically what I need is to know what entries in the KDE4 color configuration correspond to which windows system colors, or a script that will do it for me. I have found it for KDE 3, but that does not help me much and my attempts at trial-and-error left my windows programs almost unusable. I know the match won't be perfect, but I was hoping for something slightly less jarring than what I have by default.

launch winecfg and switch to the tab called "desktop integration". There you will find some options to configure the look-and-feel of your windows apps.
Edit:
I forgot to mention that you can install and select XP themes as well (in the same place as above). If you find a theme that matches the Oxygen theme a bit more, leave a post here

Thanks, the "desktop integration" tab is what I am trying to get more information on. In that tab you can set your own custom colors for different UI elements. What I am trying to find out is which colors in that tab correspond (roughly, perhaps) to which colors in the KDE 4 Colors systemsettings module.
