C100: How to Remove Green Color Cast from Tamron 17-55mm lens

[JimmyMcV]

I have mostly Canon zoom lenses with my C100. But I also have the Tamron 17-55mm, which doesn't match the other lenses in color. It adds a green cast which is annoying.

I was thinking of duping my usual picture profile and modifying the copy for use with the Tamron. Do you think it's possible to fix this problem with a picture profile adjustment to reduce the green? And how should I go about doing this properly?
I'm a little confused by the Color Matrix letters. In this case, would I be reducing both R-G and B-G?

Thanks for any help.

...how should I go about doing this properly?

Manual white balance using a neutral gray card should zero out whatever lens tints (and lighting color casts as well of course) there are. Does this not work for you?
