It depends on the type of paint and the tinting system used. Best to go to a paint shop with a color sample and let them match it. MC's red is very clean and pure in painter's terms so it's probably just clear base with only red tint in it if matched to a wet paint as opposed to the factory's powder coat.
Flame red is ral 3000 which looks about right on the charts. Do you know if the same red was used on the 90's and 00's frames? Would prefer to keep the older style if they were a different shade.
Sorry, I don't know that much. I know my 06 San An was what my Dodge truck's color code said was PR-4 (Flame Red), I also know that was a base/clear coats kind of deal, and that the color primer matters as well.
I don't know what color primer is used with that.
I can tell you that the red 03 - 06 San Ans were something very close to that.
