If you cross your eyes such as that the two boxes make one with the crosses on the same spot, you can see an optically impossible color. It can be perceived, but there is no single wavelength that will produce this "reddish green" or "bluish yellow". You can only see it by having two different neurological signals pertaining to the same spot in your vision. I've done it it's trippy, like both blue and yellow, somehow. Not green or anything, blue-yellow. Try it.
