De Coloribus / Aristoteles (B)

"Clearly, then, when sight [1] is reflected it is weakened and, as it makes dark look darker, so it makes white look less white, changing it and bringing it nearer to black. When the sight is relatively strong the change is to red [2]; the next stage is green [3], and a further degree of weakness gives violet [4]."
