On my color meter in my head, turquoise is on the left side of blue and violet is on the right side. If you go far enough left you find green. If you go far enough right you find red I suppose. I read a description once that said 'turquoise blue violet' and I thought , "gosh I'd like to see that color". I guess that's why they have color charts. But when I think of turquoise or aqua I am definitely thinking on the green side of blue. I will go find a pic of 'Stan Coates' and see if I want to grow it. Keep talking.
