I have heard lighting makes wall colors look different....is the picture with sunlight or is with indoor lamps? If lamps, maybe changing the bulbs would help. I have had several people say that their paint looked more blue than grey. Looks nice and clean.

The color as is looks very nice. There will be suggestions for you to change your light bulbs and add certain colors in decor to minimize the blue, but honestly, I've never seen that these kind of changes will transform the color to the degree you might be hoping for.

We went through 3 different gray paint colors and they all turned out blue!! I looked it up on Pinterest as to why it would turn blue and I found out that since our house faces north the shadows and less natural light turns it blue. So I looked up what gray colors were good for a north facing house and the color I picked worked. Hope this helps you!!

Did you paint your ceiling? It looks yellowish which I think is bringing out the blues in the wall paint. Paint your ceiling white - Behr's white ceiling paint is a good product.

izeve hit the nail on the head - you have yellow ceilings and that will contrast with the gray and make it feel more blue.

Thanks everyone! I didn’t paint the ceiling but I’ll try that and see if it helps. @Jennifer Hogan @izeve Is it also possible that because the walls were yellow before, they look more blue than gray? Could painting a second coat help it look more gray as well?

You should always paint a second coat, but yellow under the gray would make it look less blue not more blue if you had bleed through. How you make gray is by mixing equal strengths of the three primary colors (Red, Yellow, Blue). If you add more Yellow and less blue you get brown.

Our perception of color is never in isolation, we see color as it relates to other colors. Our brain calls respond to stimulus but can respond differently when nearby areas of the brain are stimulated. One of my favorite experiments shows that our brains can actually make us see color that isn't there at all.

Does it look yellowish in real life?

Because your ceiling doesn't look yellow -at all- on my monitor.

You definitely shouldn't base your next steps on an assumption others have made only informed by what they're seeing on their monitor.

If you're going to consider painting the ceiling and also giving the walls a second coat, it might be a better solution to put all that extra work into painting a different gray that is less blue.
