I used a Krylon Blue which one I am not sure yet till I open it up and do a look see. The supper bright white LED's really bring out the blue to the affect that I like.
I will try to this (disassemble) in the morning at work as I start to fire on all cylinders as I down the morning brew of Java.
I might still have the can on the shelf and will try to dig it out for the color used.
