PLEASE HELP ASAP

I am looking for a design template for customizing 2-5 colors of an image. Color only. Similar to 

https://www.dutchlabelshop.com/en_us/design-woven-labels/

My goal is to have an image of the product and the customer be able to choose and see in 2d the colors for the product in real time. I would love if it stopped customers from picking non contrasting colors but if this isn't simple to do it's okay. 

I included an example of a product I would like my customers to be able to customize.

 

Please help I need this done soon.
