ColourPop Buds Ultra Matte Liquid Lipstick ($6.00 for 0.11 fl. oz.) is described as a "shocking neon pink." It's a bright, medium, magenta pink with cool, blue undertones and a very flat, matte finish. The texture was lightweight, thin but pigmented, and applied fairly well. I had very, very subtle streaking along the edge where I tried to keep a crisp edge. It dried down quickly but in a time that I didn't feel too rushed in (these are still a quicker-drying formula, though), and the resulting finish was very smooth without emphasizing lip lines as much as some liquid lipsticks can. It started to crack after four hours of wear, and I noticed extra wear along the corners where the color seemed to have flaked away. On me, the color lasted for seven and a half hours and was slightly drying. Anastasia Party Pink (P, $20.00) is lighter. Kat Von D Backstage Bambi (P, $19.00) is darker. Kat Von D Backstage Bambi (P, $21.00) is glossier. Marc Jacobs Beauty Pop-arazzi (606) (P, $28.00) is glossier. Chanel La Diva (44) (P, $34.00) is more shimmery, glossier. MAC Candy Yum Yum (P, $16.00) is darker, glossier. Bite Beauty #007 (LE, $36.00) is brighter, less glossy. Maybelline Electric Pink (P, $7.99) is darker, less glossy.
