Package tray question

Wish I had access to a welder to do that, was going to use riv-studs but can't find any.

I cut the parcel tray and dropped the speakers in from the top. It looks ok but the speakers I have are alpines and free but the rings are a bit scratched up. Doesn't look horrible but not great.

Plus the tray is faded out so thinking I might spring for a new one. Next question is the car is B-5 blue in and out.

I have black seats, carpet and dashpad so sort of a black and blue theme. Buddy think the tray should be black and not blue but I disagree. Anyways what colour is correct for B-5 dark blue or light blue?
