Eucalyptus Green on the walls sets a calm, leafy mood that feels just right for a nursery. It is soft and a little grey, so it never reads loud or sugary, and it works beautifully for a baby of any gender. In daylight it leans fresh and botanical, and after dark it settles into something quiet and restful, which is exactly what you want in a room built for sleep.
To keep it light, wrap the trim, doors, and crib in Crisp White so the green has clean edges and the room stays airy. Then bring in Pale Greige for the warmer touches, a dresser, a shelf, or a single painted wall, to ground everything with a little cozy beige. In short: green on the walls, white on the trim, and greige on the furniture or one feature spot.
