Colour is no less positive than line, considered as representation of fact; and you either match a given colour, or do not, as you either draw a given ellipse or square, or do not. Nor, on the other hand, are lines, in their groupings destitute of relative influence; they exalt or depress their individual powers by association; … But the influence of lines on each other is restricted within narrow limits, while the sequences of colour are like those of sound, and susceptible of all the complexity and passion of the most accomplished music.
