I have creatures with Darkvision, who can't see light, and I'd like to be able to toggle the two on their own. I can understand why it's not a priority, since there's no grayscale mode for Nightvision. But, being able to give a player grayscale Darkvision and not the ability to see color/light would a very cool mechanic. I feel like Jumpgate being tested would be a perfect time to add this feature in.
