Don't be color-phobic! Choose a color, and commit to it. Let's say you take a hue: yellow everywhere. Saturate the entire kitchen in hues of all yellow and it works beautifully. Start with a wheat yellow or semolina hue - The darkest shade of wheat/semolina can be applied to your cabinets - for the walls, ask the paint department to custom tint the wheat/semolina hue one-half of the tint to the base paint - basically cutting the orginial color into half - lighter. For the ceiling, have them cut it down to one-fourth of the tint of the wall color. This keeps all of the same hues in one color. Apply this method to any room where you are using the same hue for the walls, trim and ceiling. Choose a wall color, and then ask for a custom mix of one-half or one-fourth of that tint for the trim and ceiling. Happy coloring!
