Here is a bluer version with the magenta removed.
I just adjusted the colour balance (Ctrl+B in Photoshop) and reduced magenta and red and increased blue and cyan.
I am quite happy with it in the original but this is a different version of the same shot just so you can see how to adjust it. See what you think.
Cheers,
Rob
ps The above technique is one of the best ways to remove any colour cast accurately
