>>12341321In physics, black is generally considered the absence of color rather than a color itself. This is because it represents the complete absorption of all wavelengths of light, while colors we perceive are typically due to the reflection of certain wavelengths. However, in art and design, black is often treated as a color, as it is a visual element that can be created and used
That, and because Google says so, I draw and something that many artists are told is not to use pure black, since that color does not exist in theory, although a black color is currently being created like a pure color, but I think that kind of black has Copyright as far what I remember
