multicoulor emitter

Hi everyone
Been lurking and reading alot of the forums here and enjoying what I am learning.
have come across something that I havn’t been able to find an answer for and helping someone may have ideas on how to achieve it.
As an example I have 2 objects 1 red and 1 blue with a glass cylinder running between them, inside this cylinder I have a much thinner cylinder that I wish to use as an emission object. Now what I am trying to achieve is where this cylinder attaches to the red object I wish it to emit red light and at the blue object emit blue light and then gradually ramp down to the centre of the cylinder where the light is white.

                 Red-------ramp down--------white--------ramp down-------Blue

Thanks Incantrix

If I got you right, you simply need to use a gradient texture node and a color ramp node (and some vector nodes top map it) :

Thanks Chameleon Scales
I was working a similar layout but didn’t even think about using a mapping node. As all I was getting was a solid change red to white to blue.
Will set this up now and see how I go.
Thankyou again
