&quot;Newton&#x27;s error.. was trusting math over the sensations of his eye.&quot;<p>A trait very common amongst scientists. I tried to explain to my peers that you could see blue as lightened darkness and yellow and red as darkened light.<p>This makes a lot of sense perceptually, if you look at the sky and the sun as it transitions from night to day.<p>But all they had to say was newton and wavelengths and prisms. That stuff is all fine, but it does&#x27;t talk about how we perceive colour.
