No, it's a lighting effect on polished aluminum. I gave the hood a slight tint of green but it had virtually no effect (pardon the pun). Most all aluminum B-24s had a black hood, though and it seems so did this one during at least part of it's lifetime. Looking at various photos of "Booby Trap" (all black and white) some portray the hood darker than others. Also, the hood paint line shifts, apparently revealing it was repainted (chances are black to green or olive drab). But thanks for the additional eye for detail.
I do believe you are wrong there Arlo. From what I know, most anti-glare panels (hoods) were olive drab, not black.
In the profile you have posted, it shows that the anti-glare panel is close to the same color as the vertical stabilizers.
In this one, you can tell it is green by comparing the color of the shark mouth with that of the AG panel. The AG panel is lighter than the shark mouth, supporting that it was green.
Here is a website with the "Booby Trap" plane in a die cast. Though the AG panel may look black, it is actually a dark dark green.
