  • the invention relates to the paint industry. More particularly, it relates to a method of manufacturing paints with predetermined colors.
  • Paints are commonly used to protect, color, or provide texture to objects. Paints can be made in many colors. In paint production, paints are formulated to a wide variety of colors using different base paints.
