So this was a continuous fluorescent bulb with a softbox in our photobooth at a nightclub.. That blue cast in the first image is just what my camera was coming up with on Auto White balance.. Which is basically a little bit of blue and green added in from a proper whitebalance. The second shot is the same type of light but with my correction of that color cast (which based on my preference still has a slight blue hint)
(Also I was shooting Nikon which always looks a lot less Red than Canon)
My best recommendation for solving that issue is to go overboard in the opposite direction, leave it there, leave your computer for 15-30 minutes, and then come back and fix it up. If I'm staring at an image that's too warm or cool for a long enough time I can never really perfect it until I "reset" my eyes to it.
