the trick light plays when it gets bored of being invisible

means Relating to or produced by a prism, especially the way light splits into a spectrum of brilliant colors; by extension, anything dazzlingly many-colored or sharply varied.

from From the Greek 'prisma,' meaning 'something sawn off' (from 'prizein,' to saw), describing the angular, sawed-looking shape of a triangular glass block. The word came into English through Latin in the 1600s, and 'prismatic' followed, blooming into its color sense once people learned that such shapes could break white light into a rainbow.
