I didn't plan on releasing another update for this, but per request, I am adding additional color options. Hopefully I covered enough of the spectrum to fit any needs you may have.
To change the room neon colors, go to the LowPolyRoom/Asset tab, and select the color you like. I have attached a color key to help you.
You'll have to change the mattress color on your own, but that's pretty easy to do. Show hidden, select the CyberPunkBed/mattress material tab, then set the defuse to the color of your choice.
Enjoy!
