My favourite browns:
Shroom (Highlight) (or Nylon if you want more shimmer)
Honesty (or All That Glitters, it's peach-ier; Malt if you want matte)
Woodwinked (a must have)
Handwritten (Crease)
Smokey Greys (very similar to above):
Gesso for matte, Crystal Avalanche for shimmer
Electra
Knight Divine
Carbon or Black Tied
