How can I change the MagicWB colors that the demon sets?
You can but you should not! The MagicWB palette is highly optimized and changing it will result in a worse look & feel of your icons. The bigger problem is that when you change the palette other programs which use MagicWB-style graphics and colors will not recognise that MagicWB is installed and will act differently (i.e. will remap and display them incorrectly or won’t display them at all). But if you know what you are doing and are an experienced user you can change the palette slightly in order to compensate for some flaws in your graphic card for example. The colors are set in the MagicWB-Demon line in the startup-sequence. They are given in the format [color#],[R],[G],[B]. The RGB values are 8-bit values.
