I love the entire concept of this car and all of the reasons behind why you are doing it. If possible I would like to offer to pay for your dinner and make a donation to your Organization.
As for color - you need to search all of the recent auctions and look to see what these cars have actually sold for and what colors seems to bring the biggest draw. You also need to find an auction house that will wave the buyer & sellers fee's.
I am pretty sure this was the TA that sold at mecum for 170,000 ( please correct me if I am wrong ).

I am looking at your build and your pretty much building a 150 to 200 thousand collar car. I am hoping that most of the parts are donated or given at a reduced cost if your goal is to get this car into the six figure mark. It kinda seems like a loss.
Okay so since I am long-winded sometime I will try to explain my next thought. Years ago my best friend started a fund raiser for Jane Bowel (
www.ridejanieride.org ) who had cancer. They raffled off a Chevelle that he had built and raised close to $100,000 the first year. Since them they have raised over $500,000 and all of the money has been given back to local family's with children that have cancer. I have been lucky enough to help the last 5 years and it is truly rewarding. This year was really hard because 4 weeks before the fundraiser one of the recipients passed away.
You may want to look at something slightly safer then an auction as it's hit or miss. A raffle is something you can guarantee. Sell 1,000 tickets for $100.00 each or 2,000 for $50.00 each
