Since you have to make plenty of other blocks and partial blocks yet, you can easily add in the turquoise with those. I only see 4 whole blocks with no turquoise, so if you make at least that many, or maybe one more or one less blocks that are mostly turquoise with only black, that will balance out the 4 without turquoise. The rest can be a blend of all sorts like the partials you already have there. I think this will be a stunning quilt when you are finished!
I think I would, IMHO, find a fabric for the turq. like the red, and stick with that, using it as sparsely as the red overall. But would like to see some blocks with strips of both red and turq. in them. I think I would use one of the black fabrics for the QAYG strips rather than the red or turq.
