How do I variate the color along one axis? So I have a laser-exhaust on my spaceship, coming out of the engines.


David already helped me variate the strength of the beam along the length, so it can taper off or remain strong along the length of the mesh.

But I also need to variate the color along the axis.

I'm modeling it after this: http://web.ccpgamescdn.com/newssystem/media/63965/1/EVE_Online_Retribution_OREFrigate.jpg

Which to be honest, I'm wondering if I need to scrap this material and try something else, but this feels above my head, I need some help.
Create a second color ramp node with the desired colors and plug it into the emission shader:
