OK, my mom wants me to tie-dye some shirts for my brother and his family in their school colors, since they often go to sports events. Colors are red and white.
Thing is, so far most of the reds I've tried have haloed some yellow. I've done them with fuschia and a bit of lemon yellow (Jacquard colors), with scarlet, with fire engine red (which went pink on me).
I toyed with trying fuschia and bright orange (if memory serves, bright orange is a pure color) to try to minimize the halo, but before I try it on this or that bit of fabric and then don't manage to get the proportions "just right" again, I thought I'd ask if anyone here has better options.
