The development of color science. Dr. Anton Trstenjak is considered to be one of the pioneers and leading world experts in the field of the importance of color for humans and its interaction with itself and with the surroundings. In the past, people were also aware of the importance of colors and were accordingly using them. Thus, for example, in Asian cultures, colors have had hidden meanings and were supposed to be used in correct proportions and for the exact opportunities, like in trading, ceremonies, stories, and others.

Some philosophies, such as feng shui, strongly emphasize the power of colors and their effect on space and the individual.

Isaac Newton was the first in 1666 to explain that colors come from light.

Through numerous experiments, he found that light is made of several different colors. When he focused the sunlight through the glass prism, out came a rainbow of seven colors: red, orange, yellow, green, cyan blue, dark blue, and violet.

Sometime later, Thomas Young discovered that white light consists of only three colors: red, green, and blue. Mixing produces white light. This is called additive color mixing. This principle is used by therapists who heal with colored light or in the theatre, where masters for light enlightens the stage.

Later on, Ewald Hering said that yellow should also be treated as the primary color because the human eye perceives it as independent, just like red, green, and blue. Black and white are also the primary visible colors. Today, Hering´s system is the basis for NCS (National Color System – natural color system).
