i can tell you, back in early summer '69, when we told Art Olson of Olson Bros. Honda/Triumph in Sioux City, Iowa we wanted a Honda 750 Four, he told us he was "getting a red and a blue one" and the red one was already spoken for, so we reserved our order forthe remaining blue-green machine which turned out to be #4779. i have always been of the understanding there were initially more blue-green bikes than red, but i don't know if that is actually true, because i suspect the red color was more of an eye grabber, so blue-green may have had less demand and sat a few seconds longer on the show room floor than the red bikes......... The blue-green color was only produced from around Mar.69 through maybe Mar.70 and then never reproduced. Some people say the 1975 GL1000 was the same color, but i do not believe this is true, i recall the hue to be different, more blue than green, if i recall correctly. I love the flashiness of the red, but the blue-green is such a FANTASTIC color, the hue changes in the intensity of light. If i had to choose between the two colors, it would be b-g. it is nice to have 4363 b-g and 232 red, but for my 2157 rider i opted for b-g. if you are convinced you know the original color of the bike to be red, it is probably a good idea to repaint same color, assuming you can provide pictorial evidence the original color is what you believe to be red. just my 2 cents worth.......
