What color is your finisher's eyes? That may sound like sarcasm, trust me, it's not. Blue eyed people see colors in a different way than brown eyed people do. Science seems to think those with blue eyes see them better, or more true. Past that a lot of things have an effect on brighter opaque reds, the most profound effect being the base it's applied to. White base will make the color really clean and bright, black or dark grey will mute it to an almost terracotta tone (brick). Red oxide primer also tends to mute bright reds and make the orange values stronger. A few decades ago the popular bright red for hot rods and modded muscle cars was Porsche Indian Red, also called Guards Red. The standard for that color was called out over a white base. Other white base call outs are Corvette Torch Red and the inimitable Ferrari Red. Last but not least, lighting is everything. Florescent lights are not all the same and some will cause minor shades to become muted. Sodium lights (those nasty blue ones) pull the base color through and make matching a difficult chore. Bright daylight is even better than direct sunlight. This is true for everything from wood refinishing to engine paint. So, what do you have? A bright red that Pontiac called Montero. Nobody could raise a right hand and say every Montero Red GTO was indentical. The color will vary just based on the different conditions at each plant's location. Very close to be sure, but not close enough to bolt a K.C. fender on a Pontiac, MI car. Black and maybe even white, but the rest, no.
