# The blue color of sky.

Hi friends,
I am confuse in Rayleigh scattering formula.
It says that the intensity of the light corresponding to a wavelength in the scatterd light varies inversely as the fourth power of the wavelength.
Hence the blue light scatters more then red light. Hence the sky seems blue. But the wavelength of violet is more less then blue so why not violet?
