I painted for many years. And now work with photoshop each day.
The selected grey was probably in the blue family instead of yellow family. Most interior colors look better if they come from the warm yellow family, including greys.
There are greys for every color in the spectrum ... from yellow to red to blue. If you pick a grey with bit of red, it will start to look mauve. Orange and it will look brown. Blues inside the grey will turn purple real quick.
Moreover, all colors and finishes are contextual and pick up surrounding colors. Especially satin-or-shiny finishes, because they pick up local colors that change intended hue. For example blue drapes will turn white room bluish. If the house next door is red, and the light comes in window, it will turn white room into pink. Green leaves, and the light from window turn white room green. So when you pick a grey that has bit of blue, the color can change for many reasons beside light bulb. Each room is totally different.
Most folks pick colors by looking at color chip in the store, instead of painting a section of wall inside home. And most folks do not ask the paint store clerk which tints are in that particular color. Sometimes the black tint will turn some bases into a bluish hue.
Go back to paint store and get another grey color from the yellow spectrum.
