I've been collecting greiges since 2011 or 2012; the very beginning is chronicled here, and I talk about what "greige" is here. I just think the combination of purple, tan, and grey is magical: it goes with everything, looks great on anybody, and is a great middle ground between neutral and vampy.
Anyway, recently I reorganized my greige collection and my nail spoons, and had some fun fanning them out. Who'd have thought a bunch of the "same" shade could be such a gorgeous rainbow?
Oh yeah, that's only half. Those are the medium greiges, another peg has my light and dark greiges.
Someday I will swatch more, and talk more about each of these shades I hope! :)
