A cool color and the hue of the daytime sky, blue is the most sedate of all colors (Figure 5). Blue can "...slow the pulse rate, lower body temperature, and reduce appetite" (The Power of Color, p.52). Designers use blue to describe ice and minty freshness. It symbolizes the heavens and divinity. It is a fairly serious color depending on its variations. Blue is the color of choice in the business world when it comes to logos and suits. Overexposure to blue can create depression, as in, "I'm feeling blue" or "I've got the blues."
