Which Colour of Warp Core?

[XCV330]

I like the blue. implies Cherenkov radiation getting out

 

[WarpTenLizard]

I never cared for the jellyfish-puke warp core. Give me the big blue lava lamp!

Blue is better, mainly because its consistent with the warp engines on Ent-D, Ent-E and the Defiant.

Purple, although it has its place, seemed advanced for its time.
