How do I know which color look good on my lips?

yeah you can always try out- and if your worried if a color doesnt look good on you… then before you buy it- you will always find some testers around… try to look at them (if there is) and try to find your shade.. if there isnt your shade and you cant open the lipstick… then try to get near a mirror and put the object on your skin to see if it matches.. sometimes you usually end up making a guess on what is good or not… but at least you learn. so yeah.. see what matches. I think I understand what you mean thou- like is your skin like tyra banks or…??? anyhoo- red is pretty but not those popping out reds, umm a shade of pink- there are osme speecific ones im sure ull find out- and you can even go for like a nuetral color would look good.. like bronzish or so. brown and bergendi ages a person like if your a teen it will make you look older.. but if you were like 30s or soo I guess it can match. ummm but for brown eyes- this is eyeshadow color but it could also maybe give you an idea for your lips- purple, green, white, dark pink, daphne, gold, soft red… they pop out the eyes or lips! you know?? well hope this helped and good luck! :)
