What is the wall color?

I’m still waiting in the color too 😊

I really like it because it’s a creamy warm neutral and doesn’t look yellow or gray like some paints do.

The color you see is not necessarily an accurate depiction of actual paint color. Many things influence it’s perception. Have a paint/color specialist look at the picture -make sure they know your north/south/east/west exposure and the type of lighting that exist in your room. Also take in consideration the other colors in your room.
