Warm colors include red, orange, and yellow, and variations of those three colors. These are the colors of fire, of fall leaves, and of sunsets and sunrises, and are generally energizing, passionate, and positive.
Red and yellow are both primary colors, with orange falling in the middle, which means warm colors are all truly warm and aren’t created by combining a warm color with a cool color. Use warm colors in your designs to reflect passion, happiness, enthusiasm, and energy
