Depends on the stage of the plant. Snow during the last month before harvest can bring some crazy colors but other than that it just melts
I don't know if I would say pointless but if the plants are starting to fade they probably wont take much water up anyhow. Are you looking to gain color?
Personally I would if they need water. I wouldn't get your hopes up on gaining anything from it though. A slow release watering and maybe a few degree temp drop.
