In this area - Inland Pacific Northwest - I've seen several pickups with tinted bedliner.
Seems to be a fairly limited range of colors, though I've seen some that matched the truck color.
Whether that's dumb luck or actually tintable, you'd best ask the various manufacturers or jobbers.
Some seem to fade, as though there's an issue with UV resistance.
We did spray-on bedliner as a side business at a dealership body shop, but only did black.
The surface was roughed with a coarse wire wheel, and heated liner applied with a high-pressure gun.
