Sometimes the patina project we work on involves the colouring of new shoes made from crust leather. Some shoe companies do have the option of purchasing a Made-to-order shoe in crust leather and then have another company to do the colouring. With crust leather, the possibilities are endless because you're no longer restricted by the existing colour of the leather. You're starting the colour from ground up, which means that you could create a shoe with a combination of very vivid and bright colours (pink, sky blue, yellow etc).
Below is a recent patina project we worked on. Client requested for an antiqued rusty green paired with burnished tips.
