People usually associate color with physical objects that are viewed in sharp contrast to their surroundings: be it a beautiful flower arrangement, or a colorful spinnaker on a sailboat against a dreary gray sky. In addition to colored objects, color is also associated with creating overall visual impressions which set certain moods, tell the time of day, or indicate certain climates or temperature. Furthermore, color can be used to create emotions or stimulate feelings such as artist’s colors in paintings and a designer’s choice of colors in decorating a room.

What is presented herein not only applies to coloring plastic resin, but also applies to all colored media including textiles, paints, ceramics, inks and so on.
