Problem with 5DMKII or just me..?

The first picture is of the 5D MKII and using lens 17-40L
Second pic is on the 60D using the 17-40L again.

Both are set on manual mode at 2.5 shutter, f/4 and 100 iso.

For some reason the 5D is always warmer. Everything on both cameras is identical. Style is set to neutral on both and WB is the same as well.

Is this just how these cameras shoot or could there be something wron with the 5D, or 60D?

Ay help is greatly appreciated!! Thank you.
