You can use Rit Clothing dye to tint the inside of clear canopys. I have done many of them.

1. Fill your kitchen sink with HOT water from the stove (Slightly less than boiling, Don't put boiling water into the sink you don't want to warp your canopy) When the water is poured into the sink the temp will drop due to the cooler sink.
2. After you fill your sink up so that the canopy will be fully covered when it is put in the water, pour in the Rit Dye and then mix it eavenly. (The water will look VERY dark but that is ok. The Plastic in the canopy will not soak up all the color.)
3. once the color is even through out the sink, Dip your canopy into the sink and hold it under the water for about 2 or 3 minutes. The longer you leave it in the dye the more dye it will soak up and the darker the color will be.

I often use the Dark Blue color and it leaves the canopys light blue. You WILL like the even color and how nicely it looks. It is MUCH easier than you might think!!!!
