Purple is not a wavelength of visible light. It is a mixture of blue and red. However, it does look a lot like violet, which is a range of wavelengths of visible light.
Brown is just desaturated orange. You can even make the same color appear either orange or brown by changing the color surrounding it. Brown exists only in our brains.
