Where I see turquoise, DH sees green and DD sees blue.
As far as commercial naming of colours there are the Pantone colours. This is a standardized color reproduction system. By standardizing the colors, different manufacturers in different locations can all refer to the Pantone system to make sure colors match without direct contact with one another.
Most paint manufacturers etc, will match their paint to a Pantone colour number, but what they choose to call that colour is entirely up to them.
This is a really interesting article about the Pantone system and how it is used by manufacturers in the goods we buy. en.wikipedia.org/wiki/Pantone
