Thanks, Diana! The living room is Behr Eon and the cabinets are stock-RTA-cabinet-nameless "white"... I've checked all the chips against it and it seems brighter than anything. I've debated just painting it the same Simply White but don't want to squander the opportunity to improve the look. My hunch is to go cooler and eggshell or matte.

Simply White is a white with a very subtle green undertone. All whites have some sort of undertone. As the poster above says, all of them will look different depending on the lighting and time of day. If you're not absolutely determined to have an all-white kitchen, go one shade darker and choose an off-white that has an undertone you do like. As the poster above said, using something that is in an adjacent room (or an off-white with the same undertone) would be a good way to go. To determine the undertone in a white, beige or gray, look at the chips on a piece of white paper without any other chips nearby. Or look at them next to each other on white. The comparison might make the undertone apparent to you then.

If there is a BM store in your area, see if they have a color consultant on site. The ACE hardware stores that sell BM paints may not have one, but the company stores are more likely to. The person in our area store will come to your house for $100 to help you choose colors. They will be able to see the formulas for each color and know what undertone they have if you have difficulty determining it yourself.

Or start buying samples and try various colors until you find something you like. If you're interested in painting multiple rooms the color consultant may be worth the money to avoid expensive mistakes. We tried ten different colors in the family room of our previous house before we found what we liked. I wish I had spent the $100 instead of doing that. :-) I am going to use her before painting the first floor of our new house.

Thanks for your detailed reply! That's great that the BM store has a color consultant. Our area only has BM at independent sellers and Ace, but I will ask. The SW consultant is limited only to virtual meetings right now, but I'm not sure how helpful that can be since it seems to me the camera is not totally reliable for gauging color.

As it turns out, I was just researching one of my options, BM Intense White, and Encycolorpedia says it is the same as one of the colors on the Behr Eon strip. I have the Samplize of that color and it still looked too dark though. I might see about getting a sample that is 50% lighter. Although I feel ridiculous for asking for a white to be lightened. :)

I think the color looks fine. The slight warmth looks good with your floors, and after you paint the door blue, that will also change the way you see the wall color. So do that first.

Worst website ever. They don't actually measure colors. They lift RGB values from 'wherever' on the internet resulting in a hot mess of numbers that mean nothing.

Does anyone know if there are tricks in choice of paint sheen or even specific undertones of other white paint that will help downplay the color shift and help keep a more consistent tone?

Colors don't have undertones. The theory that colors have undertones is based on nothing more than subjective opinion - other people's subjective opinion of what they think a color looks like to them under whatever random light source there happens to be.

As far as consistency, your brain will take care of it. The function is called color constancy - sometimes in just a few days but eventually you'll forget all about it and not even notice it.

But if you want a new color and based on the cabinets, counter top, floor, and how Simply White is actually showing up, I'd pull chips of Greek Villa, Shoji White and Agreeable Gray.

After seeing your photo, I'd try a different color. The Simply White doesn't provide enough contrast and just looks off. Check out Lori Sawaya's options--she's the color expert extraordinaire!!

There are so many posts about white paint and undertones. I painted my entire home with Behr Ultra Scuff Defense Paint and Primer, color: off white. No yellow undertones❣️ Matte on walls and ceilings, satin on doors and moldings. It applies beautifully, no issues. I have used SW and BM paint in past homes, and love the Behr. People who have visited my home always ask me: what “white” did I use, as it looks great. The white walls nicely showcase my new oak staircase and Italian porcelain wood look tile flooring.

I know this is an old post but could anyone share a photo of origami white in your home? I have very red wood floors and worry the yellow will pop and clash.
