There is SO much exciting science emerging around reptile lighting! I 1,000% agree with the above comment that one of the cool things about keeping reptiles is allowing your keeping to evolve with the science. If you're on Facebook, I highly recommend this group for a crazy wealth of information:https://www.facebook.com/groups/384134861721116 . I just had someone from my scrub python group come over to help me wire the RHP in my new bioactive setup and he seriously blew my mind with his knowledge! I've always used day/night cycles for my reptiles because I think that is just pretty basic husbandry. If they live in an environment that sees the sun, they should have light.
But the TYPE of light, coupled with the distance from the bulb is also really important (and I didn't know that until recently!). I always just used intense basking bulbs and called it all good. What I didn't realize (though it seems obvious when you think about it) is that those bulbs can be hundreds of times stronger than any sunlight they would see in their natural environment. The UV radiation can damage both their eyes and skin - just like a tanning bed, really. My scrub looooves to get as close to those bulbs as he can, just to make me mad...but after a tiny bit of research, I found out his natural habitat is in a Ferguson Zone 1/2, which means those bulbs are EXTREMELY intense. Especially on those huge, sensitive eyes.
If you feel like falling down a rabbit hole, check out www.arcadiareptile.com . They're pretty much at the cutting edge of the movement to simulate natural lighting for reptiles and they have a lighting guide that can give you recommendations by species.
And I realize none of this really answered your question, soooo...in light of what was mentioned, I would definitely steer away from colored bulbs. Darkness is necessary for proper hormone regulation and to properly set their circadian rhythm. It will stimulate more natural behaviors to allow them as little light as possible at night. If it gets cold where you are and you need to use heat at night, go with CHE's. You can easily order them online if your local stores are out of the proper wattage
