We use many words to describe the properties of individual colors and to compare and contrast them, but light and dark is the basic distinction. Without sunlight or artificial light, there is no color. We depend on light for color, which we use in countless combinations to express our ideas and emotions. The following aspects of color contain color combinations that exist in harmony with each other, and are in spectral balance. Light waves reflect red, yellow, and blue, and the rods and cones in the eye s retina simultaneously mix and sort these reflected colors into thousands of tints and shades, which work to offer endless possibilities for specific color use.
Color is both simple and complex.
It means different things to different people in different cultures. No color is seen the same way by any two people. Color is personal and universal, sending messages full of endless variations. Hot colors project outward and attract attention. The power of hot colors affect people in many ways, such as increasing blood pressure and stimulating the nervous system.
