I think you've got one bad TBC or the color balance is just way out of center.
That's a digital camera and they don't jitter like analog cameras so correction isn't needed. If you only needed one, you could go directly into input 1.
That means that you're really just trying to get them in sync at this point and can get by with one genlock to sync the second camera to the first.
Split the output of camera one with a distribution box, not a T. Ts screw up termination which would show up as either being too light or too dark.
Go out of the distribution box into the genlock in of the TBC.
Go out of the distribution box into input 1 on the Toaster.
Then run the other camera through the TBC to input 2 on the Toaster.
That should genlock the second camera to the first and since neither needs jitter correction, you should be good to go.
Normally you use a black burst generator going into both TBC's genlock input, but with a digital camera and a distribution box you can use the first camera as the blackburst generator.
If the camera has two composite outputs, forget the distribution box and run one to toaster input 1 and one to genlock in on the TBC.
Good luck.
Edit: It looks like you've got one RCA and one BNC composite output, so I'd forget the distribution box. Use the RCA to connect to genlock in on the TBC and the BNC for connection to Toaster input 1.
