Colors Are Spice For Your Eyes
One of the definitions of color at Dictionary.com is
the quality of an object or substance with respect to light reflected by the object, usually determined visually by measurement or hue, saturation, and brightness of the reflected light; saturation or chroma; hue.
That is quite a mouthful for something we can just look at and instantly appreciate. Colors are a natural occurrence. Colors can spice up a day in the mountains making it more enjoyable compared to the bland look of winter or the constant lush green of summer.
