History of NCS Colour system
We see our surroundings in colours. Our vision makes it possible to identify, separate and judge the quality of objects we look at. Colour informs us and excites us, it defines where we walk or sit; it allows us to express our feelings and our personality.
To define a colour we first of all have to describe what we actually see. Anyone with normal colour vision can see approximately 10 million colour shades, but without an appropriate colour system it is practically impossible to classify them. In order to be used internationally a colour system should be built on the theory of human perception of colours, independent of language and cultural differences.
NCS - Natural Colour System®© is a logical colour system which builds on how human beings see colours.
The scientist A.S. Forsius published in 1611 the basics of NCS system in his book „Physica“.
“Amongst the colours there are two primary colours, white and black, in which all others have their origin….In the middle there are red, blue green, yellow – and grey from white to black – increasing in intensity step by step…changing from white with brightening to black with darkening…. " A. S. Forsius, 1611
In 1920 a well known Swedish study of colours was launched, which was concluded with the development of NCS colour system. Its basics were taken from the book „Das natürliche System der Farbempfindungen“ by a German physicist Ewald Hering, published in 1874.
The primary goal of this research was to develop a colour system, based on the way human beings perceive and experience colours. The research method also encompassed groups of people, who observed colours in standard settings and rearranged them according to the similarity with six primary colours. Approximately 1 million evaluations of all shades were carried out and for final colour atlas an additional 50.000 evaluations by a group of 30 people.
The results of this research were processed by computers. Also, a comparison was carried out of human being’s “subjective” evaluations of shades with values measured with “objective” instruments for colour matrix. The research illustrated that people with normal vision experienced and arranged colours in the same way. Colour samples contain 1.950 original NCS colour shades, which are arranged in special atlases and when transferred into the environment they form a NCS colour
space.
