I decided to start this thread based on a question on Bumblebee's actual color in the movie. The Standard GM color for BB would indeed be Rally Yellow. However, In the movie He is slightly more orange. Its naturally a Custom. Digging around on line for about a half hour I got the color "Sunrise Orange" and it brought up the Paint company Valspar. Checked their auto refinishing page and got nothing. Reminded myself that House of Kolor was a subsidary of Valspar and BINGO! Shimrin Kandy Basecoats HOK PBC30 Sunrise Orange! White basecoat 3coats of orange pearl and clear! Hope this helps! I will update from time to time with new info.
