I have pretty, green eyes. I've always played up my eyes. Recently I've wanted to try the red, red, RED lip look that's trendy now-a-days. What I've learned is you can get away with bright colored lips if you keep your eyes soft. Also, wearing a more daring outfit or pairing a dressy floral dress with a leather jacket will make the lipstick match, rather than compete. If you bought the lipstick and can't stand how bright it is, try dabbing a little from the inside of your lip out until you get the hue you like. Also, swiping on a lip gloss or balm first will protect your lip from stains and leave the lipstick looking a little more subdued.
Hope it helped!
