Andrew, I tinted the upper half of them, because the upper half was the red reflector. I left the white part untinted because that's the reverse lights, not a reflector.
The black grill, meh, I don't think I like that. I want to get more of a chrome grill. Also remove the orange turn signal reflectors. I don't want it completely blacked out, I want some contrast. I like how the bright chrome looks on the front, so I'm going to go that route. With the orange removed, and a chrome grill, I think they look real nice.
Here's some examples of other guys with various chrome grills:
(this one is one of my favorite Envoys. I'm getting running boards similar to these, but paint matched my color. This is called the Bentvoy grill)
This is the grill I really want, but problem is it's like $250 for the top and bottom inserts which is kinda crack money. It's the Street Scene grill
OEM Denali grill
OEM Chrome grill
