I'm curious about the fire engine red... is there a certain red paint color that will mimic the effect of a safe light? Is there a certain pantone number? I'm thinking of taking one of the uni jr. red safelight bulbs up to lowes and having them match the color... any thoughts?

I don't know about the red but the white will change color of the walls to the color of the safe light and make the room brighter. That is the reason for making the darkroom's walls white. In my mind I think the darker colors would kill any light you would have going for you.
