To all above - I had no prior experience dyeing shoes. The Trickers were very light. The original color was acorn, but I have also seen it referenced as "burnished." It was extremely light almost a blonde color. I tried darkening it to "cognac" with polish, but the results were uneven and I was still unhappy with them. Finally, I saw a blog post by a friend who had dyed a pair of shoes, and then saw the results from RogerP's EG double monks, and thought I should give it a try. The acetone takes the leather down to the tanned hide, it does not remove the dyes added during tanning. If you look at the videos available on YouTube, you will see that you must dye darker not lighter. The shoes turned out better than I thought they would. In the end, it was pretty easy.
