Mac Redd Lipliner is an orangey toned liner, its not as opaque as Cherry but is easy to build up. I love Redd under True red lipsticks like Ruby Woo and Russain Red, it gives a little more depth to the colour, which gives a more glamourous feel.
One thing to note, I did use a lip liner for these photos since red really requires perfection. Strangely enough I only have one MAC red lip liner, which is Burgundy which I used with the darker reds here. The other lip liner I used is Revlon Redwood, which is a really old, but creamy bright red liner.
