MAC Heroine is a moderately warm-toned, medium-dark purple with a matte finish. It is a permanent lip liner that retails for $17.50 and contains 0.05 oz.
MAC Heroine Lip Pencil ($15.00 for 0.05 oz.) is described as a "bright purple." It's a magenta purple with a matte finish. I'm not as familiar with lip pencils as I am with other lip products. I don't have it, but from what I remember, MAC Magenta should be somewhat similar--perhaps a bit purpler, rather than as red as Heroine. If you know of any potential dupes, feel free to sound off in the comments!
