Heart & Seoul is described as a “warm peach.” It’s a light-medium peach with warm brown undertones. On lips, it took on a coral-pink tone with semi-sheer color coverage. It wore well (without feathering or fading) for three hours, and after four hours, there was some feathering and after four and a half hours, the middle area of my lips were without color and there was just an outer ring of color on my lips. Revlon Pink Pop is similar. MAC Kiss & Don’t Tell is lighter, pinker, more opaque. MAC Star Quality is a bit darker, more opaque. See comparison swatches.
