Found in “Discovering Colors in Prison” by Nancy Miller Gomez, “ The colors we keep caged, a stubborn brightness / refracted off betrayal, and hate” Line 20-21

The definition of refracted helped me understand the meaning of the sentence in the poem. Refraction is the bending of light or sound as it passes through something like a wall (sound) or a window (light). But I didn’t knew refracted had another meaning of the word and now it made more sense rereading with the definition.
