I haven't heard back from the customer as yet whether ornot the red was colorfast. When I cleared the work bench after shooting the new x2 red and chartreuse, I tossed the bleeders into a bag and set it aside as I was curious what would come of the colors after time. lol.
Keep in your mind's eye that this, these, were a bright blood red and clear chartreuse and a fairly strong chartreuse at that.

I have an area where pink/hot oange is a darned good summer color. I'm going to give these a whirl. Maybe all is not for naught. Eh?
