Hello, My grandfather trained with the bt2b and I have an old picture of him getting into the plane. I was wanting to change it from black and white to color but can't find any info on what the color of the plane was. I've see similar that were blue and yellow but wasn't sure for the Air Corp training BT-2B. Thanks for any information you have! I'm trying to surprise my family with coloring some of his WW2 pictures. Thanks. David
