I have done this on some of my planes. I did use the Rit. Mixed two colors together to get the desired effect. I used a large steel canning pot and kept the temp at approx. 125*. I would take the piece out about every 10-15 min to check the density. Don't want to get it much hotter than that. Some post that I've seen put some salt in the water. I did not do that. You also want to wash with soap and water the canopy before you put it in the dye. Try to keep your fingers off of it because the oil on your hands will affect the outcome. I wanted a bronze color so I used one package of orange and about 1/2 bottle of dark brown. Came out just the way I wanted it. Look at the post tinting a canopy I think you will see the picture of the outcome.
