well…is it possible? to paint like…a color that lights up (kinda like the tron lights on the suits, all the lines are neon-ish) i am asking this because it would be really useful in my current project, cuz i definitely wouldnt like to go to other programs to get the neon colors… -.-.
please and thank you 
You could try ColorizeGlow material in Standard Materials palette. You can change color, glow amount and glow radius in slot 1 of the Material > Modifiers subpalette. You will have to use Best render to see the effect.
thank you very much i would have probably taken a while to find that, it saved loads of time with my project
