Hello! Thank you for viewing my post, I am very excited to get FPD, but want to make sure it is the right option for my product.

I have a custom product that uses two different materials (metal and rubber). Each material has its own color (see attached photos).

Would I be able to have FPD allow customers to select specific colors they want for each material? Any guidance would be appreciated, 

Thank you so much for any help!

Yes, that is possible - you'll need to create two separate images layers to represent the two materials, then they can be colorized freely or through a palette you specify independent of each other.
