Anyone know how to share a procedural texture?  Whipping snow was one of my experiments for heavy driven snows in city street lights, so it's naturally colored orange.  But I just adjusted it towards the periwinkle to get the effect there.  Then used it again as a gel filter in the headlight to give the highly illuminated snow in the beam and changed that to just off white hinting towards yellow.  I was actually surprised at the powerful result.

I created it for "Bridge on a Snowy Night", but never had the same powerful effect.
