One curious thing if you understand this is to think on purple. Purple is blue+red, but like you pointed out 2 colors should give you the average wavelength, which in the case of blue+,red should be green. So why the hell do we see purple as something different? Well, that’s because humans have 3 sensors for colors, roughly corresponding to Red, Green and Blue, triggering both Blue and Red without triggering green at the same time gets interpreted differently than green, even though it shouldn’t. Which means that purple is not a color, but rather a mind trick your brain plays on you.



No, I cheated. I figured out that it needs to be solved in layers, and figured out how to solve the first two layers,but could never figure out how to solve the top one. Eventually I looked up how to solve it and reproduced the movements. I can put it in order now, but I wouldn’t say I solved it since I’m doing movements someone taught me not that I figured myself out.
