Why the colors are visible to human eyes?

Answer 1

The colors give the body energy.. Most colors have various amount if light in them coming from a rod of invisible energy. The energy in these colors is what helps us ejaculate during mating occasions. nah im bsing

Answer 2

A color is not a physical quantity. Therefore the answer is simply that colors are visible to human eyes because our brains interpret the visible spectrum using colors. Colors are a construct of the brain.

The color space for humans is three-dimensional, meaning that we can make every color we can see by mixing three prime color (usually red, green, blue). However there are creatures which have a color space of a much larger dimension, meaning their colors require more than three prime colors. Such colors are difficult for us to imagine.

Likewise there are also creatures with a smaller color space, for example animals which can only see in black-white only have a one-dimensional color space.

The dimension of the color space (and thus the number of prime colors) is related to the way the human eye works. Our eye has three types of cells sensitive to some section of the visible spectrum ,each corresponding to a prime color.

Also note that there is nothing special about the visible spectrum; we simply call part of the electromagnetic spectrum that we can see (because the cells in our eyes are sensitive to them) the visible spectrum. There are animals who can see for example in the infrared. These creatures can possibly see color in the infrared.

Answer 3

Colors are visible to human eyes because of the presence of photoreceptor cells called cones in the retina. Cones are sensitive to different wavelengths of light, allowing us to perceive a wide spectrum of colors. When light enters the eye and stimulates these cones, signals are sent to the brain to create the perception of color.
