She was an olive drab color all over with an anti-fouling red color below the waterline (the waterline itself was not painted black or anything). Here's a link to an article on building and detailing the kit (also the PT-117 version) as another 80' Elco boat:

The Elco PT boats (and I think the Higgins too) were constructed of plywood... including the decks… so you may want to fill in or sand off the planking if you’re a stickler for accuracy.
Hope this helps! It's a fun kit to build, enjoy!
