So I have made a custom shader that uses R for spec, G for smoothness. That means I am not using an RGB spec for my spec PBR shader, just greyscale. Anyways, it seems like I really have to crank up the spec to get it so I can see clouds/trees very clearly on my blue tractor hood. I think it's ok to compare this to a car hood. So the problem is, when I turn up the spec it basically is lerping it from a blue hood from the blue albedo color, to a mirror at the other extreme. However if you look at the attached picture of this black car, you can see the clouds as if the hood was a mirror, yet it's still black retaining the cars color. I just can't seem to wrap my mind around how all of this works.
