This is my 1971 FJ40. The paint is original. I have the original Toyota window invoice sheet, and it lists the color as "Capri Blue". The pre-delivery paperwork was dated June 11, 1971, and the plate in the door jamb is dated April 1971.
I mention the date because some sources mentioning color state that Capri Blue was only used through 1970, and was replaced in 1971 by Horizontal Blue.
If I can find the specific color code from the vehicle, I'll add it to this post. I'm not sure so far of exactly where to look. I don't see any other plates in any obvious locations.
