I bought a few cans of light taupe to paint over the peach color in our bathroom. After painting the walls the color on the walls ended up being a light gray. At first I thought it had something to do with the lighting in the room but it’s not.
I brought into the bathroom the can of taupe paint, a taupe color-sheet sample, and a small piece of wood that I painted with the new paint. Everything looks the correct color in this room except for the walls themselves.
So, is this an issue with the old paint bleeding through? Should I have used primer or something first?
I think you are right. The original peach color is bleeding through and effecting the new color. You could try another coat and see if this will truly cover the old color. If not, then priming is you only option.
