Best is of course to use the preset setting of the white balance to get a correct white balance before taking the pics (like Onslow said).

For the images you uploaded, it's clear that the blue channel is way too dark. So it would be better to restart from raw.
But as it is, one of the best investments you can make is a plugin from Harald Heim's called ColorWasher. Easy to use and really outstanding in quality.

Yes, $50, but there is a demo.

This was done with it in one, two three. Say what you want white (or neutral) and done.

There are no Borg. All resistance is fertile.
