But they are, or else why give them names? White is the presence of all colors at the same time, black is the absence of color, grey is the combination of the two pigments.

Black is the shade of objects that do not reflect light in any part of the visible spectrum.
Scientifically, black is not a hue (color); a black object absorbs all the colors of the visible spectrum and reflects none of them. This is sometimes confused with black being called ‘a mixture of all colors’, but that is not the case. In fact, an object emitting or reflecting all colors is perceived as white. Sometimes black is described as an “achromatic color”; in practice, black can be considered a color, e.g., the black cat or black paint.

Because, in physics, the true colours are made of a single wavelength of light. White is all wavelengths together, so it’s all colours. Black is the absence of light, so it’s no colour. you can’t get grey light (only grey paint or whatever).
