Reds convey warmth, strength and energy, and are bright, cheerful and inviting. Create the feeling of a warm sunset, of walking on a brick road. Paired with a variety of other colors, red can convey a wide range of expression from hot to warm, elegant to outrageous, modern to traditional.
Orange combines with the warmth of red, and the cheerfulness of yellow, and is a reminder of the tropics. Yellows are bright, cheerful and full of life. Perk up any color scheme with yellow, and bring to mind a happy, sunny, outdoorsy feeling.
