No, actually it's only one shade of red. Trust me, after 35 years in the commercial art and photograhy I could show you 10 individual color swatches that you would call red but if I laid them out side-by-side you would see that they were all different.
If you are deciding on a color (any color) to paint your truck have the paint mixed to match a swatch from a color chart... and look at the colors in daylight. Fluorescent lights give off a green color light and incandescence give off a brownish color light.
Color is one of the most esoteric and misunderstood subjects you can imagine.
