ColourPop Pillow Talk is a neutral-toned, medium brown with a matte finish. It is a permanent lipstick that retails for $6.00 and contains 0.0352 oz.
ColourPop Pillow Talk Matte X Lippie Stix ($5.00 for 0.035 oz.) is a muted, medium-dark brown with subtle, warmer undertones and a matte finish. It had opaque color coverage with a very smooth, velvety consistency that glided on effortlessly, but the texture did feel a bit thin and clingy once on. This one highlighted the natural texture of my lips slightly and would visibly pull apart when I widened my mouth or smiled. The color lasted for six hours with slightly more fading from the center of the lips. It was somewhat drying over time. Make Up For Ever Neutral Beige (107) (P, $20.00) is lighter (95% similar).
