I would also be happy to see more turquoise. I bought a tourquoise summer jacket last year, but that's about the only thing I have in this colour. It looks more greenish than your examples above though, so would you still call this turquoise? Maybe it's a bit like the tiffany blue you mentioned in the HEWI thread?
I am often a bit unclear on colour names that I read here on YLF, for example where does beige end and cream start, and what's the difference between toffee and camel colour? Is this only me? I would find it helpful if you could make a blog post on colour naming, Angie. Googling does not help much, see below my results for beige.
