I needed to dye a pair of white satin shoes for a client and was sure that I had just ruined the shoes when I first applied the dye.  It looked like it was going to be splotchy with darker and lighter patches.  Imagine my relief when the shoes were finally dry (24 hours) the color was an even shade of beautiful blue!!  I did use a Q-tip to get into the stitching (it worked better than the brush) and I used blue painter's tape to protect the natural leather sole from the dye.  The shoes look as if the satin was blue before the shoes were put together!!  I'd be confident to try any of the other colors in this TRG line.
