For a subtle hint of colour may I recommend the yummy range of lip butters by Korres. They add just the right amount of colour to lips giving a healthy look without being heavy. All natural ingredients, they are incredibly moisturising and stay on for a reasonable amount of time.
Personal favourites are Wild Rose and Pomegranate, an instant pick-me-up for our miserable weather.
