You're leaving D Color/Iconoid open right? If you close them down, you'll lose the font colour changes. They need to be running at all times.
I wasn't but I am now. Tried Iconoid again and set it to start with Windows and minimize to the tray. Fortunately I don't have many start up programs. Thanks Clasurol.

Just tried Desktop Icon Toy as it was recommended by someone here, can't remember who though, I read so much stuff yesterday. Anyway, gonna go with it, seems to work really well and has a lot of options
