Product color groups on shop page

Hello, I’m trying to implement a setup where we can associate several colors to one base color. As an example we have about 15 different colors of red, 20 different colors of blue, etc.. This make it challenging for the use to filter. Ideally, we would associate the 15 different red colors to a single Red color thumbnail, and the same with blue, green etc. Does anyone know of a plugin or a way to do this?
