St. Lucia Teal vs Duck Green in Real Spaces
3 real rooms side by side. Seeing St. Lucia Teal and Duck Green in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
Living Room
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. St. Lucia Teal reflects noticeably more light off the walls, making the space read more open than Duck Green.
Bathroom
