You really didn't give enough information. What other rooms can be seen from your kitchen? What color is the countertop? What color are the appliances? What type/color is the floor? Do you eat in your kitchen? IF so, what is your kitchen table like and what do your dishes look like? Are you willing to repaint your sunroom? Do you love the bright yellow sunroom? How much wall space is in your kitchen? If you paid an interior decorator to come to your home to help select a color for your kitchen walls these are all questions that she would ask and the answers would help decided the new color.
