Horrible yellow theme in Messaging after latest Galaxy s5 update

I just downloaded the new software for my Samsung Galaxy s5, under at&t. Unfortunately, my home screen for text messages is this absolutely awful yellow/orange and it's driving me nuts. Is there any way to change it? I've looked through the settings and I can only change the background within a text (the white background on the home screen is terrible, too) and the type of text bubble. I don't understand the one with the air balloons, but at least I can pick something else. The yellow/white is too much, though. I'm an all-black-everything kind of girl.
