Guards Red
He told me whenever he bought a red 'Vette that needed repainting, he used Porsche Guards Red. The cars looked as good and usually better under all lighting conditions indoors and outdoors, and sold faster than those with the factory shade.
Riverside Red was a "pure" red, as used on Formula I Ferraris that only "pops" in bright sunlight, where it looks great. It is near the low-frequency end of the color spectrum, and low-frequency lighting (like flourescents) can't pump up the color like incandescent bulbs or sunlight. Some darker metallic blue Mopars have the opposite problem, turning almost violet under some conditions. This why used dealers car lots used to string incandescent bulbs across their lots; they not only made sparkly reflections, they brought out truer-to-daytime colors.
Roman Red may be a different story, maybe someone else has experimented with different options and can report.
