Why are black and white not colors?

Because one absorbs the light, the other reflects it.

Colors are created by light: light consists of electromagnetic waves. If they hit an object, they are partially absorbed, i.e. swallowed, and partially reflected, i.e. thrown back. A yellow car reflects the yellow light, a red flower the red. That is why we perceive them as yellow or red. But this only works because the white light contains all the colors. The trick with the prism: If white light hits a prism, the entire color spectrum that is contained in it becomes visible. From red to orange, yellow, green, blue and purple. Water droplets work in a similar way. Therefore, when sunlight hits a wall of rain, we see a rainbow. Black swallows all light: normally black things are not 100% black. Black velvet swallows most of the light. A black T-shirt looks dark gray next to it. White throws back all light: even white walls, leaves or shirts are never 100% white. Fresh snow throws back a lot of light, which is why it looks dazzling white. Nevertheless: We now know why black and white are not considered colors in physics. Nevertheless, in everyday life we ​​can speak of white as a fashionable color or black as a mourning color.

Some color specialists refer to black, white and all the shades of gray in between as achromatic colors because they do not contain any color. Achromatic colors are rare in nature. Even the gray tones of stones usually still contain a little color.

We consider black to be elegant and refined, but also the color of mourning. In some Asian countries, however, white is the mourning color. We associate white with purity and innocence.

Light is energy. Because a black T-shirt absorbs the light almost completely, the fabric heats up more than a white T-shirt, which reflects the light and thus the energy.
