Weapon Retex Laser Sight Help?

[Neuromatic]

I've recently started trying my hand out at weapon remodeling and retexturing, and I'd say I've mostly got the hang of it. However, there's this one little detail I haven't been able to work out - retexturing weapon laser sights, like the one on the 10mm pistol. I've checked all over the internet for tutorials on this specific matter, done experimenting myself, but have never found anything. What I basically want to do is change the color of the laser from the laser sight, from red to blue.

 

If anyone knows how exactly you do this, I'd be very grateful if you could help.

Think that is done within the model itself I remember doing this with Enclave doors etc. The Emittance color from one of the NiMaterial nodes if I recall.
