Yes, she refers to it as Turquoise and a few other places, too, and I think once as Peacock.
It's probably just how color presents on my monitor, but it looked a lot more like Peacock than Turquoise. I went downstairs and grabbed a tube of each color and brought them upstairs so I could replay that segment. Honestly, it looked like something in between the two colors. I wouldn't have given it another thought except that she had lined up yarn from other projects in Season 2 and Parrot uses Peacock, not Turquoise. I could be wrong, but I think the only other Season 2 blues were Navy and Royal Blue.
Wouldn't it be grand if this was the biggest concern any of us have? They are both lovely colors.
