See, I would have guessed that the #76 is in an orange shade, it looks lighter than red to me. Much like the #44 car. The #63 does look yellow. It's really tough to determine the different shades of white from a single black and white photo. Especially with the sun light and shadows being what they are. You may also want to post this in the NASCAR forum where maybe somebody will have firsthand knowledge of the cars and drivers your looking for. I wish I could help more.
