As far as I know, Windowblinds can not change Desktop icons text color. As a test, If you uninstall "Microangelo on Display", reboot, what color you get on your desktop icon text?
This is what I see on my desktop with Corporate applied. No "Microangelo on Display" needed for me. There are dark drop shadow around the text so I can see the text perfectly.
