Though more common in the bedroom, the bathroom, and the living room, blue can be used in the kitchen to astounding effect. It could stand as the main color scheme, or as the accent color, as shown in these excellent examples:
Blown glass pieces
No repainting or redecorating necessary: simply rummage around the house -- or the furniture boutique -- for a set of blue blown glass bowls and a vase or two. Use them as accent- or centerpieces amidst a kitchen made of light wood.
Blue napkins or tablecloth
And again: use blue as a complementary counterweight or accent to wood. If your kitchen's made of a rougher, darker, and more rustic kind of wood, opt for light blue. Use table napkins, cloth place mats, or a tablecloth. Opt for a fine, checkered print on the cloth, for added texture.
Indigo with rich red wood
A shade of blue like indigo, or iris blue, should work like a charm with rich, gleaming, reddish wood. Consider repainting the ceiling as well for the full effect.
Grayish blue with white
A light, grayish blue wall -- tiled, or brick -- should work well with a white and light gray color scheme. It proves a versatile palette, where you can add a pop of color with just about anything -- or, in this case, a vase of red flowers.
Powder blue accent with wood and gray
A chic, urban kitchen replete with bare wooden floors and concrete drywall will pop out with a powder blue accent. It's a suitably soft and soothing counterweight to the urban textures.
Persian blue cupboards
Paint over your cupboards with a nice, even coat of Persian blue. Best paired with light wood trimmings and white or light gray walls or tile.
