How Many Names Are There For Grey?

The Inuets have over 100 words for snow only a handful of words for snow, so shouldn't Pittsburgers have more than one word for grey during the winter months?  I tried to remember back to my box of Crayola crayons to see if I could start a trend, but could only come up with a few names/shades.  After seeing some of the pictures I took on my walkabout, you will see what I mean about it being a grey day.

 Towards the end some colors started to pop, but nothing too crazy. 
Pittsburgh is pretty into Buff and Blue despite the Steeler's colors being back and yellow.
