"Reflection nebulae appear blue pretty much due to the same reason why the sky is blue and this is due to scattering. But how does scattering work? The simple answer is that the light that is thrown out from a star, or our Sun, is reflected. Light that comes from the Sun and most newborn stars is called white light and it is made of many different colors - very similar to a rainbow. When this light travels passed particles of dust, the blue light (or if you want to be scientific; wavelength) is scattered."
If you are reading this, you are awesome, and I wish you a happy and prosperous day!

The nebula is illuminated by the light of nearby stars.  The shorter, blue, wavelengths are scattered along our line of sight. 
Would you know my name, if I saw you in heaven?
