I don't know about the colours, but I'd go with the theory that the colours in MAC's promo pics can look off rather than them having the sizes look different.Thanks, Naynadine!!! I was thinking it is based on the size but couldn't quite figure which EDSF based on color story description. May be in much more trouble than I originally thought. Thank God for the holidays as I already started to strategize (plot) for this collection!!!
