sets with no grey pieces?

[Sucram]

I was thinking about this before, i was wondering if theres any lego star wars sets with absolutely no grey pieces? light grey and dark grey both count. and polybags dont count obviously.

....excluding polybags, I'd say this is very unlikely for ANY lego set.

Looking through my own collection, seems highly unlikely given that many sets will have either technic pins or flick missiles, especially vehicles.  Location based sets mostly using earthy colours so a bit of grey in those is understandable too.    There are probably not that many (modern day) sets in any theme that don't have some grey pieces.

Quick look through sets on Brickset shows 7194 Yoda only has around a dozen grey parts from a total of 1075 and Darth Maul only has 2 grey technic pins from a total of 1868 parts.
