Speaking of purple, that is a goof night camouflage colour.

GURPS Powers: Enhanced Senses handles this effect by having it take time to adjust to a lower lighting level to only suffer the default penalties; I believe the penalties are doubled when your eyes haven't adapted, and indeed exposure to brighter light can ruin it, requiring readaptation. I forget how this interacts with the Night Vision Advantage (or if the book even explores this); my inclination would be that a character with Night Vision 2 (for example) only needs to undergo adaptation for light levels below -2. Assuming I'm remembering correctly and it is indeed a doubling, this means when someone with Night Vision 2 is in an area with -5 Darkness, they're at 2*(2-5) = -6 rather than -10, and once they adapt they are at -3. Sudden light exposure will ruin the adaptation, leaving them back at -6.
