I need someone help in developing a formula for a homework assignment I am doing with a patent leather shoe. The shoe is a red patent leather high heel shoe. The assignment is requirements are: Using a regular microfiber cloth, what formula is needed to change the red patent leather shoe to a pink with rubbing the cloth on the shoe (the heat from the rubbing of the shoe will induce the heat to trigger the color)? 2. Once you rub the cloth to the shoe and change the cloth, the shoe will have 72 hours to stay pink before it goes back to its original color (red). Is there another formula that needs to be implemented (think of a moon ring / technology) How will the shoe change back to its original color ***Remember, the shoe will not change color by the rain or sun, it will only change color by the microfiber cloth. The shoe must keep the gloss once it change color (must stay patent leather). Must know a formula ( or if its technology must know a way to make the color stay for 72 hours). The formula has to be accurate with an exact amount or weight. I have to take this to the lab to test it. Budget is negotiable
