Just realized my whole hallway looks better because I swapped one light bulb
I changed the bulb over my hallway mirror from a 5000K daylight LED to a 2700K soft white one about two weeks ago, mostly because the old one felt harsh at 3am. When I held the two bulbs side by side the paint on the wall looked greenish under the cool one and warm cream under the soft one, same exact can of paint. I always figured color theory was a screen thing, but that one bulb swap made the oak floor and the navy towels actually work together instead of fighting. Now I'm going around the house checking every bulb against a paint swatch taped to the wall, and I've got three rooms that need fixing. Has anyone else picked their bulbs by Kelvin only to find out the room already looked warmer than they planned?
We repainted our living room two years ago with Behr's "Polar Bear" and I swore the color was wrong for months, turns out we had 4000K bulbs in the ceiling fan the whole time. Swapping those to 2700K did not fix anything though, it just made the room look dingy and yellow to me, like a hotel from 1998. Warm light hides dirt and makes everything look soft and cozy but it also kills contrast, which is why your navy towels suddenly "work" with the oak floor, they stopped popping and just blend into a warm blur. I'll take the greenish cast at 3am over a room that looks like it's lit by candlelight at noon. Cool bulbs make whites look white and colors look like the can you bought, and if your paint reads green under 5000K that is the paint being green, not the bulb lying to you.
