I just did mine in RIT navy blue with a hint of black (first attempt) and then red (2nd ws) ... both turned out great, although the blue turned out a bit hazy (IMO). Red one took a while to get right; had to re-heat the dye several times. The one thing to remember is not to get the mix hotter than 160 F, otherwise you'll deform it and then have to waste time trying to "form" it back. I used a metal clothes hangar and shaped it to fit the outline of the canopy, which helped keep it's shape better.
