I heard a rumor that firearm frames in FDE, OD, etc are weaker than the standard black frame due to less carbon black in the mixture to absorb UV energy.
Is there any truth to this?

There probably is a minor difference, but it's also a very small difference.
My background is in plastics, I've working in injection molding and blow molding for 12 years now. Plastic in it's natural state is a milky translucent white (think milk jugs). That will be your strongest polymer, so even adding black weakens it somewhat. But like I said, it's a small difference.
The chart in the link shows various mechanical properties of natural, red, and yellow with the same polymer. Don't take these as gospel truth, as changeling the polymer or specific masterbatch will give different results, but you can see how the properties can vary some by color.

Article by Jim Tarr who states that its a loud YES,IF the color material is put into the mix of polymer.I heard a rumor that firearm frames in FDE, OD, etc are weaker than the standard black frame due to less carbon black in the mixture to absorb UV energy.

The topic created a question for me you may know, what is it that makes PVC ultraviolet resistant and why does it seem UVR PVC is usually not white?
