White light is made up of 7 colors. Red colour, due to its longer wavelength does not get scattered by the particles in the atmosphere and hence reaches our eyes more distinctly than the other colors.

if a light is having shorter wavelength then it is scatterd because of the sunlight partivles present in the atmosphere and thus for a light having longer wavelength should least scatter

The red light scatters the least because it has greatest wavelength and hence it travels the farthest . Thus red light is used as indicator.
