Fog Light Fits 1989 Oldsmobile Cutlass Ciera

I'm not happy with the fulfillment of my order. The product is a replacement fog light lens. I need 2 replacement lenses one for each side, driver and passenger. I received a mismatch selection of lenses. The back part of the assembly is black a powdered coated almost enamel baked on finish. Quite nice actually and I want to believe done purposely to add quality to the product. However when the selection process took place I only received one of the black backed lens and the other is a bare metal backing lens, no black powder coating or enamel looking finish for the lens. Now my concern is the reflection of the light will differ from one lens to the other. Same bulb in each lens yet a different color because of the difference of the lens back color, one being black and the other a bare metal non color backing. If it makes no difference I wouldn't know, but I believe it was colored for some reason and I do believe they should match either with color for both sides or non colored for each side and shouldn't have one and one causing mismatched lenses for sure and possibly different lighting color emittance for my fog light use and or application.
