There’s some possible history further back in our languages where kala might have meant darker not just black. Similarly the etymology of Krishna (the deity) is both considered “dark” or “black” depending on whom you ask. I suspect it may be a case where our languages at the time didn’t need to delineate between black and a dark colour. Tone/shade was a relative unlike hue.
