Reflection nebulae are not glowing plasmas but are visible because of light from nearby bright stars scattering off of dust particles. The nearby star or stars are not hot enough to cause ionization in the gas of the nebula but are bright enough to give sufficient scattering to make the dust visible.

Near a bright star, clouds of these dust particles scatter short wavelengths of visible starlight more readily than long wavelengths, producing lovely blue reflection nebulae. Nine of the more spectacular examples of these dusty, blue stellar neighborhoods have been assembled here by astrophotographer Rob Gendler.

Just weeks after NASA astronauts repaired the Hubble Space Telescope in December 1999, the Hubble Heritage Project snapped this picture of NGC 1999, a reflection nebula in the constellation Orion. Like fog around a street lamp, a reflection nebula shines only because the light from an embedded source illuminates its dust;

Reflection nebulas are huge clouds of dust which reflect the light of nearby stars. Like emission nebulas, reflection nebulae are also usually sites of star formation. Reflection and emission nebulas are often seen together.

This applies to dust particles in reflection nebulae or cigarette smoke. At the end, the sulfur grains are so large that they no longer favor any particular wavelength of the optical spectrum and the scattered light is white.

Reflection nebulae are clouds of dust which are simply reflecting the light of a nearby star or stars. Reflection nebulae are also usually sites of star formation. They are usually blue because the scattering is more efficient for blue light.
