These finishes are really good for super pale people, go too pink or beige in flat opaque colours and the results can be very unflattering. If you're at the other end of the spectrum and are super tanned, these sheer shades also look gorgeous and compliment a healthy tan perfectly.

This picture shows what happens if you go too light and matte with your nude lip. 'Son of a Peach' is a pale cooled toned pink, that for my colourings is far too pale and is definitely a contender in the perfect concealer lip category!
I hope this has helped you out a little and steered you into finding your perfect nude lip shade!
