those are so pretty.
it's weird because the gloss is clear. when i put clear closs on, it still kind of changes color. i guess that's photoshop for ya or somethin!
first one:
put a purple pigment (mac's violet piggie) and then a gold one (like golden lemon) in the middle and clear gloss over it. just have to be careful not to mix.
2nd one:
a pinkish pigment (fuschia) on first. then layer on a darker purple on top, but concentrate more on the outer parts of the lips. then clear gloss
3rd:
start off with teal pigment in the center. then a bright green piggie (or maybe sprout e/s), then golden lemon piggie, then basic red matte piggie with clear gloss on top.
i've never used mac's mixing medium before, so i'm not sure if they used that to apply the stuff first.
