history: Red is such a passionate, vibrant color Oh, that's nice. It sits next to orange at the end of the spectrum of visible light. It has the longest wavelength from what I can remember! I don't know if it's the longest, but its dominant wavelength is around 625-740 nanometers. That's long, I guess! I know that violet has short wavelengths.
