ColourPop Secreto Ultra Matte Liquid Lipstick ($6.50 for 0.11 oz.) is a muted, medium-dark, reddish-copper with warmer undertones and a matte finish. It had a faded quality to it and coupled with the matte finish, it was harder to dupe. The texture was lightweight, spreadable, and thin but was not too runny. I was able to apply the color evenly across my lips, and it dried down within 30 seconds. The dry down wasn't forgiving, though, and it emphasized barely-there flakes (this was the last in a swatch session of 15, so my lips are about as smooth as I can get 'em!) and "cracked" slightly along some of my deeper lip lines. It lasted for six and a half hours but was drying over time.
