No, you're eyes aren't tricking you. Everything really does have an orangey tint. CS3 doesn't have a cool "sunset filter," so I had to do the best I could with transparency effects. Turned out okay, could be better, true, but I'll work it out eventually.
Silly past-me, you don't need a filter, just the right maps.
And Photoshop CS3... wow, that was a long time ago for me indeed. Mind you, CS6, while the last CS version, is far from the latest version of Photoshop, those are the CC's now. Never used them.
