MAC e/s: Soba (everyday lid color), Creole Beauty (newest favorite), Coquette (perfect match for my eyebrows)
MAC pigments: Tea Time, Rich Life, Cocomotion
Others: Rapture by Smashbox (amazing dark brown, the texture is divine), 04 Flexi Brown by Bourjois (from the "ombre stretch" eyeshadow release), Cocoa Puff by Too Faced (from the "Natural Eye Kit" and "Natural Eye Shadow Duo")
Sorry I couldn't stick to just three - I love browns too much
