I have fairly pigmented lips and Squirt just looked like someone had pissed all over my mouth. In terms of nude lipsticks, I use Myth for an extreme toning-down (it's the palest MAC lipstick I've seen, and a very clean concealer shade with no pink), Blankety (slightly darker, slightly more grey), or Honeylove (the darkest of my nudes, warmer, rosier). I tend to reach for Myth the most often as it has good staying power but doesn't dry like Honeylove's Matte formula.
