I don't know to be honest. It's not my photo (sorry, I'm not a great photographer) I suspect you're right about the color coming from elsewhere though. Here's another photo I lifted off hte internet showing how the steaks should look while raw, but after they've been beaten (you'll know they're ready to flour and fry when they look like this)
This works for tougher cuts of beef steak and bison too (it's actually a southern US adaptation of German schnitzel)
