red is a good choice for dining
Red has been shown to raise blood pressure and speed respiration and heart rate. It is usually considered too stimulating for bedrooms, but if you're only in the room after dark, you'll be seeing it mostly by lamplight, when the color will appear muted, rich, and elegant. Crimson can make some people feel irritable; if you love red but it bugs your mate, try small touches in accessories or upholstery fabrics.
Orange, like red, stimulates appetites. In its pure form, however, orange may be a difficult color to live with. Terra-cotta, salmon, peach, coral, and shrimp are more popular expressions of the hue. Peach is nurturing yet restful in a bedroom; in a bathroom, it flatters light skin tones. Orange shades imbue a living room or family room with warmth and energy. In a kitchen that faces west, however, orange tones may feel unpleasantly hot.
Yellow captures the joy of sunshine and communicates happiness. It's perfect for kitchens, dining rooms, and bathrooms, where happy color is energizing and uplifting. In halls, entries, and small spaces, yellow can feel expansive and welcoming.
