I painted it dark green and added two lamps. Best decision we made.
The sunroom was white when we moved in. Bright white walls, white ceiling, original white-painted wood floor. It flooded with light in the morning, which sounds ideal and was, in fact, brutal before coffee. It also had no visual weight — nothing to rest the eye on.
I proposed painting it dark green. My husband's response was that painting a sunroom dark would defeat the purpose of a sunroom. I argued that a sunroom doesn't have to be a greenhouse — it can be a cozy room that happens to have lots of windows.
The color I chose is a deep forest green — not black-green, not olive, but fully saturated forest green. The ceiling is the same color as the walls. This is a move I'd been hesitant about but had seen done well in houses older than ours. It works because the windows are large enough that even with dark walls, the room is light-filled during the day.
The lamps were the final piece. Two matching brass floor lamps, one in each far corner, aimed slightly toward the center. At night, with the lamps on and the green walls, the room feels like being inside a lantern.
My husband now refers to it as his favorite room in the house.
The paint transformed the room, but the lighting sealed it. Replacing the flush mount with a proper ceiling fixture made the green look intentional rather than just dark.
The lighting decision connects to our approach — see the post on why we start every renovation with lighting.
Why Dark Worked in a Bright Room
Counterintuitively, the deep green made the glassy, light-flooded sunroom feel better, not darker — cozy and enveloping in the evening, balanced by abundant daylight by day. A pale color had left it feeling washed-out and unfinished; the dark shade gave it character and a clear identity.
Lighting a Dark-Painted Room
Dark walls absorb light, so we added more warm sources than a pale room would need — lamps and sconces at different heights with warm bulbs — so the room glows rather than dims. The result is moody and inviting, exactly what a sunroom that's also an evening retreat should be.
