Samsung says it went with the color scheme as it incorporates a touch of gentleness:
Pink Gold was chosen as it, like the other colors available for the Galaxy S7 and S7 edge, is a natural color that provides a sense of comfort. These hues glitter and shimmer as if illuminated from inside their glass surfaces.
In particular, the refined, skin tone-inspired Pink Gold color scheme is intended to soothe and incorporate a touch of gentleness, radiance and sophistication to the smartphones' design.
The pink color option is now available to customers in South Korea, and Samsung mentions that it will bring the variant to select markets.
