I recently uploaded a small batch of pics and those two pictures got rejected for some colours problems. Not that I'm complaining, it's only that I don't really see what the problems are nor how to fix them. Being colorblind myself, some color casts effects might escape me as well, so I'd like you guys to point me out what's wrong with the following rejections (and how to fix it!):

Quoting Globalpics (Reply 5): I can't offer any more advice on top of what the others have said but, mate they are awesome photos, well done specialy the First Air thats a crisp photo,I really hope it make it into the site Smile
Thanks for that, I appreciate it.
Anyway, I still have no clue for the First Air shot. Perhaps a screener could tell me what to do, and how to fix this shot? I'd like to see it in the databse.

Does quite an improvement, if you're interested in fixing it.

It is neither necessary or even a good idea to use all three colour controls as two are always acting against each other and only two are need to correct any cast. It takes some knack to get used to but the first problem is assessing any cast. Using all three does not help in learning how to correct casts !
By pressing Ctrl+B in Photoshop the colour control sliders come up with options to adjust the levels in the highlights, shadows or mid tones.
Using the Mexicana as an example, this is difficult, not a straightforward image to correct as it is basically a white balance problem.
However, the first thing that hit me was the red/pinkish cast at the top of the fuselage, very unnatural. I ticked highlights and -14, 0, +6 corrected that.
The image was then left with an orangey cast which I corrected in the midtones with -9,0,17
The shadows had taken on a slightly cyan cast which was corrected with +5, 0, 0
You may need to repeat these actions as the controls do have a slight effect on each other and the result here still has a slight cast on the top of the fuselage, though much better.

Sorry, forgot about the top one.
That has a much more subtle cast, but the sky has a cyan cast, (cyan=blue/green) As we are all aware skies are rarely green !
It was dead easy to correct, far easier than the Mexicana at +16, 0,+6
(note the zero on all of my adjustments, only two controls ever being used)
