M.,
I love to paint. My mom and grandmother both painted. I learned to paint and wallpaper (Yes, Wallpaper, in small doses, is making a comeback.) from them. I paint and repaint my house. I am no professional, my husband would tell you I watch a lot of HGTV. I do love color but don't know anything about it. The best advice I've heard about color, specifically kitchen color , is to think about food and what you like to cook. If you love making your own homemade sauce, think red. If you love to bake bread, a golden hue. I personally love deep veggie colors, red peppers, eggplant, asparagus. I chose a color called Artichoke.
I also tend to like earthy and rich colors. My living room is a dark squash color. Think about what you are doing in the kitchen that you love to do and choose a color that would mirror that. If you don't cook think about how a certain color would make you feel while you are in that space. It's not about picking a color you think looks good in a space it's about how that color makes you feel within the space. Just remember it's only paint and if you don't like what you choose change it, it is only paint. Paint just a square and live with it for a while. Then paint it or try another.
