But with that wouldn't it skew all the colours in the video? Red would become purple, yellow would become green... I think what she wants to do is adjust the colour levels (RGB -> just the B channel) so that all of the colours become tinted towards blue, not mixed with blue as I'm thinking the transparency method would do.
Nope, not at all. If you set the setting to "Multiply" It'll be fine. None of the colors will change except, they will look bluer...=P
I made quick tinted images using both methods (mine and the matte suggestion), the results:

That's the original frame, not messed with at all, straight out of premiere. You might have to copy and past the link to get the image to show, so here's the address:

Again, you might have to copy/paste the address to get the image to show, here's the url:

As the link title implies, this is the tinted image of the EXACT same frame using premiere's matte using a blue screen with a multiply transperency with the cut off set to 13.

As the name implies, this is the color corrected version using Photoshop's Color Balance options.
In my opinion, the best looking image is the one done in Photoshop. It is much more vibrant and not so dead like the premiere version. Keep in mind these are very very quick color tests, so fuck around with the settings in premiere and photoshop and see which you like best! I personally find Photoshop to be an advantage over premiere's filters.
Anywho, Hope I helped.
