Relax Fellas, it is just an example, it is an usability thing; Im not saying that Ubuntu Should be BLUE/GRAY, im just saying that TOO much Orange is not easy to the eyes. Having Orange Icons, With an Orange wallpaper after a few ours on your pc is not good for your eyes, it is about finding the balance. Ubuntu should be able to be beautiful without any modification from it's default installation. All I can say is that Elementary Icons could be use a LITTLE Orange tones, but not as main colors, however it was an example of what im trying to say.
