RYB

Remarkably Red color a primary participate in additive and subtractive combinations of colors resulting in various shades unlike any other primary color is unique. It is interesting to note how Quran came to mention Red in particular while describing the spectrum of colors along with the information of its various shades adding up to White and subtracting down to extreme Black! Human or God? I would like to find out how uncommon it would be for someone to put this combination together while emphatically commenting on spectrum of colors in that age and time in history.
