- Do you know, how the color reduction works exactly?

- Let's see if I got this right.
-
- 0-3 -> used by WB : 4 colors
- 4-11 -> used by MagicWB Deamon : 8 colors
- 252-255 -> used by WB : 4 colors
-
- This leaves 256 - 16 = 240 colors for the picture.
-
- You want me to but all those pens to 0,0,0, thus reducing the colors in the
- background pricture from 256 to 240 colors, right?

- TIA
