Sorry, but we can't see undertones on a photo because everyone's monitor is different. What would look like a purple undertone on my computer, would probably look more green on someone else's monitor or pink on a third person's monitor.

Plus depending where in the room and what else is affecting the color can change a color. So if it's near a window with trees, it can appear more green. Or if your room next door is red, it could appear more purple.

Here is what I mean. Every center green square is exactly the same color. Notice how the color surrounding it changes the look and feel of that green? Color is always affected by what is nearby. It is affected by the time of day, the window exposure, etc.

So the same color in the morning will look different with natural light, than in the evening with LED lights or with florescent lighting.

According to Maria Killam, gray has three undertones: green, blue and purple http://www.mariakillam.com/what-everyone-should-know-about-gray/

maybe her method will help you see it better.

Here's the prime example of why we can't tell you what the undertone color is or even exactly what the color is.

In photoshop, I took 1 sample from each of the four photos you posted and put them next to each other. They are in the same order as the photos you posted. So tell me what color is your wall?

benje, gray can also have a brown undertone, a red undertone, even a yellow undertone. I'm a fan of Maria but I feel a lot of times she tries to simplify things a bit too much.

Here for example are 4 grays sampled on photoshop from the exact same area. The only difference is that the first one is sampled from greens, the second yellows, the third reds and the fourth from purples. I didn't bother with the blues or oranges.

Very hard to say but I am guessing purple.

Another factor may be your eyes. I have slight cataracts and I see things more yellow. Hubby has lens replacements he sees things more blue/ green.

Very educational, cpartist, thank you!

I disagree with Maria too. Her goal is to sell her books and services. Her advice is geared towards partial info.

When I was testing grays on my walls, 70% of the grays had yellow, red or brown undertones. Red was a predominant undertone that I saw.

If you check with the paint companies, red is a primary additive especially for Sherwin Williams.

@MDnavs, it helps me to put a bright white sheet next to the color and colors with other undertones.

I was looking at black yesterday and the undertones were all over the place.

I agree with beachem that it would be more helpful to see undertone if you compare it to a white sheet of paper.

Also, as cpartist showed above, undertone is relative; if you compare four grays you can compare their undertones. I don't know as much about color as cp, but my guess is that comparing to complimentary yellow isn't the best approach.

With the gray trend, a lot of people painted their home exteriors gray. One was my across-the-street neighbor a few years ago who didn't see the purple undertone in her paint choice until she had purchased several gallons and painted the front of her house. It didn't bother her enough to redo, but a purple gray exterior certainly wasn't the look she was going for.

I see blue in the first shot. Maybe a little rosy looking in the second. Yellow in the third. Green in the last.

Try looking at a clean bright white chip against it to exaggerate the color.

I agree with cpartist and others. Very helpful examples too. I, personally, see blue undertone on the first pic, purple on the second and third, and green on the fourth..

First, monitors. No accurate representation

Unless it's a professional photoshoot with special umbrellas and stuff..or somebody extremely talented in photography that is very knowledgeable at how to work with the light present. (I saw one person like this. So I know they exist. But it was her profession)

Second-color changes like crazy. Same room even-different light, different angle, different shadow, different colors around

Good at least you both see gray

Because our backdoor entrance is a shade of green and my husband says it's purple..)))))

I agree with Anglo. Ask for the formula. I was just in the paint store today because the blacks seemed red to me. The BM black had tons of raw umber in it.
