Adding to my post above, I took another look at the test piece that I
heat set and I didn't notice it before, but the green as well as the blue did not wash out completely. It's much more faded than the blue, but not completely gone like all the other colors.
I know that these aren't meant to be used by heat setting them, but while experimenting with them, I thought I'd see how they did under these conditions. Just wanted to pass this along in case it helps anyone!
