I've got it. The final exterior color and a complimentary color for details. Were we standing in the home depot paint section where I pulled these samples you'd be looking at Citronette, HDC-MD-03 the olive color on the left, and Sovereign, HDC-CL-06, which is kind of an eggplant-ish dark purple. Both from the Behr "Home Decorators Collection, thank you.
The olive shade will be Pandora's exterior color. It may be a tad darker but for the sake of discussion but this is it. The purple lives on the opposite end of the color spectrum, making it a nice choice for pin-striping, the roof, and/or interior color. The primary colors of the interior will live in the worlds of bamboo and barkcloth, two materials I've dabbled with in the past. So there you have it.
Although I'm not picturing anything as elaborate as the reference picture below, I would like to make use of tiki style matting for the headliner. The barkcloth would make great curtains, front door panels and loose throw pillows and perhaps a detail wall. A couple of cool light sconces a small Edgar Leeteg-inspired black velvet painting and bingo. We've got a polynesian vibe. Vantiki.
The other color/texture I'm strongly contemplating is Pearl white, for seating cushions and to keep the interior feeling light and bright in spite of the bamboo and woodwork
accents. The accompanying shot to the right is a good example. Picture the side interior panels in a padded barkcloth, the headliner in bamboo matting and the seat cushions done in diamond tufted white vinyl.
