How Casco Bay changes with the light
Casco Bay is a deep color. In north-facing or dim rooms it reads darker and cozier; in south-facing rooms it shows more of its color. Either can work, depending on the mood you want.
North-facing rooms
Casco Bay will read even deeper in north light: great for a cozy, enveloping room, less so if you want it bright.
East-facing rooms
Casco Bay will look warmer and brighter in the morning and cooler and grayer by afternoon; check a sample at both times.
South-facing rooms
South light keeps Casco Bay from feeling heavy, so deep colors work well here.
West-facing rooms
Casco Bay looks cool in the morning and warms up in the golden late-afternoon light.
