Borrow a little blue starlight
Follow white starlight through dust. Add grains and see scattered blue light leave the direct beam towards a different viewpoint.

White dots: direct starlight · blue dots: light redirected out of the beam
A qualitative scattering model. Real scattering depends on grain size, wavelength and viewing angle; the model does not infer grain properties from this photo.
