I think on the MELT GALS...IN the promo pic...it shows true to color on her because she is very fair skinned...and im sure she also used a MAC liner too .
Im more carmel so it shows close like hers in the promo..but just a lil bit less intense...so i think using a liner will make it close like the promo pic. lol...
but i think anyone darker than nc 43 or nc45...all MELT lipsticks are not gonna look like it does on the melt girls ..cause they are very fair...so they i think will be much brighter on them...and plus im sure they did some camera touch ups too. but still .
