The banana is absorbing red and green light, but not blue. It appears black when illuminated with a blue light.
A ripe banana will appear black when it has overripened and started to decay or when it has been exposed to extreme temperatures.
It appears red. That's the main reason it's called "a red cloth".
A blue object appears black when illuminated with light because it absorbs most of the light that hits it, including the blue light that gives it its color. This absorption of light prevents the object from reflecting enough light to appear blue, making it appear black instead.
A red sheet of paper will appear black when illuminated with cyan light, which is the complementary color of red. When the paper is exposed to cyan light, it absorbs all the complementary color wavelengths and reflects none, making it appear black.
I'm assuming green because yellow and blue mixed together (I know you aren't mixing colors) makes green. It might just look like a yellow cloth under blue light, with no change at all. But I could be wrong.

Black lines in banana bread are typically caused by overripe bananas that have oxidized and turned dark during the baking process.

Ripe bananas are typically yellow, although some varieties like plantains may have a different color when ripe. The peel may also have some brown speckles or patches when fully ripe.

Yes, it is generally safe to eat black bananas as long as they do not have any signs of mold or rot. The black color indicates that the banana is very ripe and may be sweeter than a yellow banana.
It is a blend of black and yellow. The size is huge and it's very poisonous also.
