Mask the logo layer to split it vertically. Duplicate the logo layer, and set its mask mode to subtract. You now see the entire logo again. Apply the Fill effect to one of the layers; the logo fills with red by default. Using the eyedropper, change the fill color to anything you choose on the screen. Repeat the process for the other layer.
Thanks for your help Dave! I've done as you've said but don't quite understand when you say mask the layer to split it vertically - do you mean mask one half with the edge of the mask down the middle? Because I need it to be dynamic across the whole logo, so the whole logo would be the other colour (pink) when on the other colour (blue) and vice versa.

It would have been good to know that sooner. In that case, make a solid and duplicate it. Each horizontally so the right edge of one is adjacent to the left edge of the other. Position both to match the vertical split in the background.
Use the solids as track mattes for the logo layers. If the logo itself moves, you're done. If the background moves, you'll have to parent the solids to the background.
For further information on track mattes & parenting, go to AE's online help and enter the appropriate search term.
Okay, I've almost got it... Just messing around with the track mattes. Thanks for your help Dave.
It would really help to see the logo or something like the logo. If you start with a gray logo you can avoid blending by simply using blend modes. You can try Overlay or Color. You can also use Preserve underlying transparency to isolate the color effect to just the logo. These two layers, the Background and the Logo could then be pre-composed and a duplicate of the background placed below the pre-comp and rotated 180º. It should take you about 2 minutes to set this up. I did it in a little over 40 seconds.
