How do I only change keyboard theme?

[ThirdWheel]

I installed liberty mod and then MattedBlues theme, and I set up everything perfectly to my liking, except for some reason the keyboard (gingerbread) is black and red and sticks out like a soar thumb. Please let me know how to only change the looks of the keyboard without messing the rest of it up. If anyone has a keyboard style that looks good with MattedBlue then that is a bonus!
