This design has to be one of my favorites as far as how well the colors came out. At least I think. I am partly colorblind so sometimes I just don't see colors the way everyone else does. Blues are especially bad for me and this one has plenty of it.
I really like the way the orange looks like a lantern in shape but also how it appears to be illuminating some of the other bars around it. Very cool glowing effect in my opinion anyway.
Very little post processing has been done to this image. I didn't have the gamma set correctly when I rendered it so I had to adjust for that in Photoshop, but otherwise this is just how it was when it was done (with a black background added obviously)
