Drying at 50F

So warm days and cool nights can change the color of buds to pink blue or purple coloration. 70 degree days, 50 nights. I did this my final week of flush to blue dream. Some top buds turned a little bit of dark blue, not enough to satisfy me however. I was curious if I dried them at 50 degrees if it would help to color them more? Any ideas? Am I asking for mold or drying problems? I have a humidifier, oscillating and exhaust fan I can control. And I can control heat, but the goal is coloration.

no, once they're cut, they're done...may get some slight color changes as chlorophyll breaks down and some underlying coloration is revealed, but that was always there.
different Flavinoids are responsible for coloration, and if they aren't there to begin with, all the A.C. in the world won't help.
anthocyanin is responsible for blues and purples, lycopene is red to purplish, carotene is orange, anthoxanthin is white, Chlorophyll is green....all cannabis has a large amount of chlorophyll, obviously, but it's the ones that have a high concentration of one of the other flavinoids that will truly "color up"...

mine changed colors cause genetics. Day temp max 81 average 78 low 72. Night temp average 66. I'm curious about the terpenes content in my plants. I'm going to find out how to get it tested.
