This has a surprisingly huge effect on the success of colours you choose to paint in your home. Have you ever put the right colour on the wall or a furniture piece, but something still felt off? You may have had the wrong finish. Something with a bit of sheen could have been better if you went full glossy. Or something too shiny really could have been softened with a nice matte finish. The remedy is the same with trying to get the right colour — pin up or paint a sample of different finishes when picking a colour to see it in the space and in the light.
