Rookie Paint Questions

[66 C10 383]

I've got a 66 C10 with the 536 Dark Aqua Poly paint. The remaining paint on the truck is original but not in very good condition. I've tried to hand polish it to get a good idea of the actual shade. I've never seen a truck this color in person and the online pics look like anything from darkish green to a medium dark blue. I do realize online pics can't or won't show true colors anyway.

Does paint type have anything to do with the actual true shade of the paint? If it's painted with a bc/cc will it still look like the original shade? I might be wrong but won't the gloss from the cc throw it off making the paint look different? I'm thinking an acrylic enamel might end up being closer to the actual factory shade. Also, with good paint coverage, the primer color shouldn't matter should it?

I'm not going back 100% original with the truck but I'd like the body to look as stock as it was in new condition in 66. Especially since this is considered a rare color for 66.

I've never painted a car before but I've got a friend who's done some non-metallic painting so I might try my hand while doing the firewall. I'm torn between using the original color from an online place in a spray can or buying a quart and using a spray gun with his assistance. He's leery since he's never sprayed metallic though.

After trying the firewall, I may try to spray it myself one panel at a time, or just biting the bullet and let someone like Maaco paint it. It's going to be as low budget as I can get by with as finances are tight.

Can you guys give me some thoughts and ideas? Oh yeah, as an added challenge to this, I don't have access to a paint booth and will probably be lucky if I can paint it in a garage … Hopefully I can get the firewall painted to see the actual shade of this color and go from there.
