19:07, that's gorgeous!
Our basement is a light taupe with lots of white trim, white painted fireplace, ORB fixtures, and navy accents. It's also a man cave and that's what DH wanted. I'm planning more fabrics to add soft color to the navy- like the green- blue above. Lots of light really makes the difference, and we open the shades every day. It doesn't feel dark down there, despite the taupe and limited sunlight.

Upstairs, we face northwest so don't get tons of sunlight in the living room. I used red oak hardwoods, white trim and wide wood blinds, and painted the walls a warm pale yellow. It really helps- it was all a weird pinky beige before (ceiling, walls, trim all same- nasty!). I used behr plus cream puff and polished pearl throughout the main level and will keep it as long as we're in this home.

Ours is all white with a blue accent wall like this.

OP here. Thanks for the replies. I am not concerned about the all white will look to clinical. I have made all white interiors look good before and am confident I can do it again. (I respect the fact that others don't like that look). I was mostly curious about tricks to brighten the basement that are consistent with all white, or an alternative to all white that brightens the room even more. Thanks.

All white is perfectly fine -- the trick is to introduce *texture*; otherwise it will look too cold. But an all white basement won't look like an all white upper level

I agree. The previous owners of our home painted the basement all white, and it was cold and sterile-looking.

We painted it a light taupe and it made a huge difference in the space. Use any color, even an off-white, but not pure white.

All white looks too clinical. Warm it up a bit. It's a basement -- it's ok.

I would go very light, but not all white. beige floors, light paint--pale yellow or a warm off white, and white trim and ceiling

It sounds like a hospital room. Our basement is a wheaty yellow that is cheerful without being too bright. White trim. Lots of recessed lights. It seems to work.

I like all white. But I have also used BJ Weston Flax to warm up a room and I liked it. Not too yellow.

I second the lighting and mirrors suggestions.

If you can swing it financially, adding an egress window makes an INCREDIBLE difference.

NO! It will make it seem cold! You need warm colors and very soft lighting.

We have a dark (northern exposure) living room. When I was looking into paint colors, I read somewhere that white is actually not that great for rooms that get little sunlight, because it will seem gray. I can definitely say that that is the case with the currently white walls. It's supposed to be better with a medium-light color. We'll paint the LR a light yellow.

Would light that is cool / blue-ish (6000 kelvin) instead of warm yellow (2700 kelvin) help or hurt?

Good lighting can help. In lieu of installing new lighting fixtures ($$) put higher wattage lamps in the fixtures.

For my own enjoyment and with an eye of possible resale in a couple of years, I am doing a minor renovation to my rowhouse basement, which has limited natural light -- new whitish floor, white paint trim, off-white paint walls, very light wood doors, and other minor things. I like the all white look and I think I know how to make it work while avoiding the dreaded "institutional" look. Two questions:
1) Is an all-white basement the key to make it as light as possible? Are there other tricks to make it light that don't rely on paint or floor color (e.g. mirrors)?
2) Any suggestions for resale? I am not concerned if the buyer doesn't share my taste for all-white -- houses here sell in a couple of days with multiple offers, so I am sure the fact that the walls are off white and not, say, the buyer's favorite shade of canary yellow will not be a deal breaker, as that's something the buyer can easily change...
