Does someone know if this is purely a property of languages and their evolution or if there is a biological or neurological foundation for this? I understand that you could make names for colours as fine-grained as you want with visible light being a continuous spectrum, and at the most base level there is only a concept of "colour" without further distinctions. But to me it feels like the major divisions as we know them in English are intuitive beyond language. Surely when you look at grass and the sky you feel you need different terms to describe them?
