Is it possible to dye clouds?

The question is as in the title: **is it possible to dye clouds?**

For example, suppose I wanted to take a white cloud and dye it red. 

What would I have to do in order to accomplish this?

I see no reason you couldn't by aerosolizing strongly dyed water, but you'd be restricted to very pale, pastel type colors due to the rampant scattering caused by so many tiny droplets. Think of a piece of colored, hard plastic. If you make a big scratch down the middle of it, it gets much lighter, if not becoming completely white. The rough surface of the scratch scatters the incoming light and interferes with the absorption effects that would colorize the light. So yes, you could probably alter the color of clouds in a tiny way, but they will always be mostly white in direct sunlight.
