Except no human (non-colorblind at least) past three years old thinks bananas have the same color as the sky (see the example given in the repo, that's a mistake literally no human could make)
"The color of the daytime sky is commonly blue. The common household fruit that is also blue would be blueberries. Blueberries typically grow in acidic soil. The pH of the soil they grow in is usually between 4.5 and 5.5."
Also this problem I first tried to solve myself and I couldn't because I imagined sky to be light blue and blueberries are very dark if blue at all to me.
