We are looking to create something similar to this: [login to view URL] We want it to be able to integrate to our Wordpress website and allow people to customize the colors of their braces using a pre-set color palette we provide. We would also like to include a few "done for you" options incorporating a few local sports team colors. This option would be a separate button that would automatically fill in the colors for them. Looking to do this on a stock photo similar to the one provided on the website above. Also, if possible looking to find a solution that would allow people to upload their own photos to customize their actual teeth. Basically, we would need the ability to upload a photo, overlay the braces on it, and allow for customization using pre-set color palette. If this is something you can accomplish, we're looking to get started right away.
