I bought paint when I started my remodel and it has been seaveral months I went to paint and it’s purple can I return it for the color it was soppost to be a gray

Take it back to store to shake it up if u don’t have tools to stir.

Try shaking it up or stirring it with the power drill attachment. Usually if paint gets off colored it means it's settled.

Like Gail said you need to call the store first to see

It's probably settled and needs to be stirred up again

You need to call the store to get an answer
