How is this possible?

There are no words, everything is on the image. How is it possible to set 1 color of computers like this? Or was it possible in previous versions and now it is not? Or is this a memhack?

I figured out how to do it. It's crazy. It's hard to explain. If anyone is interested = write, I'll answer someday.
