Yes, original paint for a 1978 RD400, at least in the US. It was the only color available in 1978 and the '78 was the only year they did the seat with the body molding at the rear. 76-77 was different.
Looking at the chart you attached, it's the second column from the left, 3rd from top.
I'm going to take my tins off, find a different set, get a Laguna seat, and do a yellow/black power bar paint job like a Kenny Roberts TZ. That's the plan anyway.
