Explore "Non-Perception of Colours" by Samuel Taylor Coleridge on Textopian. Read with annotations and highlights.
What is said of some persons not being able to distinguish colours, I / believe. It may proceed from general weakness, which will render the / differences imperceptible, just as the dusk or twilight makes all colours / one. This defect is most usual in the blue ray, the negative pole.
I conjecture that when finer experiments have been applied, the red, / yellow, and orange rays will be found as capable of communicating magnetic / action as the other rays, though, perhaps, under different circumstances. / Remember this, if you are alive twenty years hence, and think of me.
