Dual monitor with MBP Retina 13, one monitor is slightly lighter in color than the other

I ordered two of these monitors recently, and I just tried them out today. I am using two mini-displayport to displayport cables to connect my laptop to the two monitors. For some reason, one monitor's colors seem to be slightly lighter than the other.

I'm having a bit of trouble getting a screenshot/photo of this coloration issue, so I dont have one attached. Is there something wrong in the way i have my setup? I've even done a factory reset on the settings for both monitors to make sure it wasn't some issue with a setting, but that didn't seem to help. Any tips would be appreciated!
