I'm glad it worked out for you Ringo. I've been playing around with purple lake and indigo and making every shade of purple known to man lately. Getting the exact color the first time is probably the most challenging part since there are so many shades that you can potentially make. Anyhow, I think the wig looks great, and I'm glad you posted the formula you used.
I've hidden my phone humber somewhere in my cosplay gallery. If you find it you can call ^_^. J/K or am I.......you'd better check........
