How To Edit Player Colors
From OPU Wiki
To edit player colors you need to edit the palette infomation in the color.bmp which is in the maps.vol file.
In this example I will change the color of player 1 which is blue. I will replace it with a solid red. And I will replace the red of player 2 with a solid green.
First extract all the files from maps.vol.
Open color.bmp with IrfanView. Goto Image > Palette > Edit palette..
The default palette
Double click on the squares to select a different color for the square index.
Blue is colors index 0-23, Red 24-47 and so on.
Once you have edited your palette press OK and then save the file as color.bmp.
Repack your maps.vol with the new color.bmp and all the other files you extracted.
Move your new maps.vol to Outpost 2 dir then run.
