It does seem like the Color Whisper range is being discontinued, which is sad, because I greatly prefer these to Revlon's Lip Butters. The Color Whispers have a smooth, luxurious feeling on the lips, and provide a beautiful shine. They have to be re-applied fairly often, but that's par for the course when you're using a shiny, sheer lip color. They're perfect for those days when you want a lip look with some shine, but don't feel like dealing with both a lipstick and a gloss.
I own two shades, Pin-up Peach and Mocha Muse. Pin-up Peach is a pretty, natural pinky-peach, but it unfortunately contains a lot of shimmer. It's not bad by any means, I'm just not about shimmery lipsticks. Mocha Muse is a GORGEOUS true beige-y nude for light skin, which I would definitely purchase again.
