Well, this one, there's two reasons. There's two factors involved here. The sky, for instance, rarely scattering. And other colors, like red and yellow, for instance, because they have long wavelengths. They pass through the atmosphere pretty much undisturbed. Blue light, which is what we see in the sky, is a shorter wavelength. And it bounces off gas molecules. And it's a much the same size as the wavelength. The blue light bounces off and gets scattered around. And that's why you see more blue lights than anything in the sky. Now the clouds just dropping. They're subject to what's referred to as me scattering. Or is here in Italy, I'd be a scattering. And the water droplets, they're large. They're fairly large. And they'll scatter all the different colors of sunlight. So this type of scattering depends on the size of the water.
