Twig is best described as a brownish pink but the brown is very subtle. I used this lipstick in my last no mirror make up video (http://www.beautybulletin.com/videos/makeup/no-mirror-makeup-4-amina-parker).
On me its a lot brighter because my skin is dark so it stands out a lot but on someone more fair it would be a very muted pink, almost nude color.
It has a satin finish so it is really creamy on your lips. I do have to constantly reapply though since it does not have a matte finish, it transfers onto coffee cups or just disappears as the day goes. I do not mind though since mac lipsticks lasts me ages and its a beautiful color.
Its one of those shades that can suit everyone because it is very natural but has a slight pink tint.
I paid R180 for this lipstick and I definitely would repurchase it.
