> Well no, it's turquoise, that's why we gave it a whole different word.

For some people "pink" does not exist as a concept, it is "light red". In English we talk about "light blue", but an Italian may talk about azzurro (galazio (γαλάζιο) in Greek; kachol (כחול) in Hebrew). Is azzurro its own colour different from "blue" for everyone, or only for Italians? Is "pink" a different colour than (light) red?

Before the different word of "turquoise" was created, did the colour still exist and/or be perceived?

If a language/culture does not have a word for "blue" does that mean the colour does not exist?

Where does "white" end and "grey" begin? Where does "grey" end and "black" begin?
