Many objects do appear black or white when light falls on them. If they are black, it means that the object is absorbing all wavelengths of visible light and not reflecting any. If they are white, it means that they are reflecting all wavelengths of visible light and not absorbing any. The color of an object is due to the wavelengths of light that it reflects.
Black objects absorb most of the light that falls on them, so they do not reflect any specific color. Instead, they appear black because they reflect very little light that is visible to the human eye.
Objects that absorb all light appear black because they do not reflect any light back into our eyes, making them appear void of color.
Black objects absorb most of the visible light that strikes them, reflecting very little light back to our eyes. In white light, which contains all the colors of the spectrum, black objects absorb all colors equally, appearing black to our eyes.
When light falls on a black surface, it gets absorbed rather than reflected or transmitted. This absorption occurs because the black surface does not reflect any of the light that hits it, converting the light energy into heat energy instead. This is why black surfaces appear dark, as they do not appear to reflect any light back to the observer.
A black ball would appear black in red light because black objects absorb all colors of light and do not reflect any. Therefore, in red light, the black ball will not reflect any light and will appear black.

Since blue objects absorb the green light, the objects appear black.

The grass would appear black under orange lights because green objects appear black under light that does not include green wavelengths. Orange lights contain little to no green light, causing green objects like grass to absorb most of the light and appear as black.
Objects that reflect all colors of light appear white because they are reflecting the entire visible spectrum equally. When all colors are reflected, they combine to create white light. This is in contrast to objects that absorb all colors, which appear black because they are not reflecting any light.
The saying "black is not a color" implies a certain meaning of the word "color" which has nothing to do with whether objects can appear black or not. It basically comes down to a question of semantics, which has a lot more to do with language than it does with physics. Ultimately, "don't worry about it" is probably the best answer.
black
White reflects light better than black. White objects reflect most of the light that strikes them, while black objects absorb most of the light and reflect very little, making them appear dark.
We can directly observe light sources and objects that reflect light. Since space contains little of either, it mostly appears black.
