The original Naked palette has warmer golds and browns, making this ideal for olive or darker skin tones.
The Naked 2 palette has more silvery/taupe-y colors so it is definitely for cooler complexions- anyone with "paler" or pink undertones.
And the newbie of the bunch, the Naked 3, is a great mix of warmish/coolish shades, so really anyone and everyone can wear them. Most of the colors have a mauve/pinky hue and in my experience, I don't know a single person who doesn't look good in pink. And if you think you don't, then you just haven't found the right shade yet!
