Deep Blue Light

[Bpat]

Is it possible to have blue light and not that lifeless white bulb light?

YES!

If you want blue light in your house you can achieve that by placing shotguns with light attachment on places.

How? Place some wall weapon holders under the floor or hidden behind walls(so it doesnt look bad)

You will probably need to use cheatstick to spawn shotguns/ shotgun attachment/flashlight attachment, cos farming all that....well you can, but....yeah
