Going clockwise around the color circle, wavelength increases as you go from blue (450 nm) to cyan (500 nm), to green (550 nm), and so on. In between red (650 nm) and blue however, lies a quadrant of nonspectral purples. Are the wavelengths of these purples below 450 nm, above 650 nm, or something else altogether?
