I am not finding a reference, but I think I read that Newton chose the word "spectrum" by analogy with the word "spectre" (which means ghost), since the rainbow colors were sort of "hiding" in the white light and were revealed by the prism. So it is not a coincidence that you can make puns like on this comic. Rps (talk) 17:59, 13 September 2023 (UTC)
