Fixing Color in Video taken thru a Window

Question

Poor dummy me! I have taken some footage through a window in Abu Dhabi in a tall building.
The window must have had a slight tint in it.
The footage appears to be slightly green & blue.
I have played around with various effects in PP, all to no avail.
Can some experienced editor play around with it and let me know the best settings and indeed the best effect to use
to correct this footage. I have enclosed a still of the footage & embedded code from a small video sample on
Youtube.
I am going to use an adjustment layer as there are several sequences . Using PP CS6
Thankyou

Colour correction, which doesn't require complex compositing work, can be easily done in PrPro.
Working in high bit depth yields better result, so tick 'Maximum Bit Depth' flag in your sequence settings (as well as in the Export Settings when you're done) and utilise 32-bit effects - you can filter them by toggling '32-bit Color' badge in the Effects tab.
Set your workspace to Color Correction so as to monitor scopes and waveforms while manipulating effects' settings. Understanding waveforms and scopes helps you realise what you need to do so as to achieve desired look.
Waveform of a well exposed footage with deep contrast occupies a wider range, whereas one of a footage with a weak contrast - a narrower range. So as to expand the contrast for the latter case you need to lower the 'bottom' (black point) of your waveform closer to '0' and lift its 'top' (white point) closer to '100'. You set the black point with either 'Pedestal' or 'Input Black' and white point with either 'Gain' or 'Input White'. You compensate for overall brightness of your footage after you tweaked the Pedestal and Gain with Gamma.
Waveform also clearly shows you which channels' settings to tweak and how in order to achieve proper colour balance. The more R, G and B waveforms aligned, the better the colour balance.
Here is an example for all the above with RGB Color Corrector:
