There is no current blood test or scientific method to accurately measure and classify the biological colour of a person’s skin, hair and eye pigmentation.
There is also no current scientific process to accurately determine the colours and tones which harmonise with a person’s skin, hair and eyes.
The genetic pigmentation of human skin, hair and eyes – colour characteristics – interact dynamically to define a person’s colouring, their look.
The colorDNA system defines a person’s colouring as their colour expression – a unique colour expression.
Every person’s colour expression is different and changes throughout their life.
It is most vibrant before the aging process and the loss of natural proteins and pigmentation begins.
The peak time of vibrancy is different for everyone and increases or decreases with the combined effects of health and lifestyle.
To scientifically profile human colouring, a number of challenges need to be overcome.
There must be a range of three-dimensional colours and tones large enough to include the diversity of all human skin, hair and eye colours.
There must also be a process by which the colour qualities of each colour characteristic can be separated, identified and classified, individually and as a combination.
Human colouring is not definitive; it is organic, biologically alive and in a constant state of change due to a person’s health, the aging process and individual lifestyle choices.
Therefore, the colour system requires an algorithm and artificial intelligence to organically follow people as they change.
A human colour classification method must be based on the same colour principles which are used worldwide by artists, designers, education and business to classify, identify and match colour.
These colour principles include the colour wheel first created by Sir Isaac Newton.
colorDNA uses the 12-step colour wheel to identify the colour categories into which a person’s skin, hair and eyes are classified. The colours are referred to in the colorDNA system as hues.
Value is referred to in the colorDNA system as tone. It identifies lightness through to darkness of each colour characteristic.
Chroma is referred to as variable saturation. This term identifies the level of dullness to vitality of the skin, hair and eyes and also describes the level of saturation and evenness across each colour characteristic.
In addition to the colour wheel, value and chroma, Johannes Itten’s methods of identifying and classifying contrast are the fourth identifier used by the colorDNA system to classify human colour expression.
Contrast recognises the different levels of juxtaposed hue, tone and variable saturation within a person’s skin, hair and eyes.
The three colour elements of hue, value and chroma, now referred to in the colorDNA system as hue, tone and variable saturation, plus contrast are known within the colorDNA system of human colouring as colour qualities.
The three colorDNA qualities from each of the skin, hair and eyes are separated, analysed and classified.
The classification method is achieved by a sophisticated structure of principles, algorithms and scientifically controlled three-dimensional colour palettes.
The colour qualities create a person’s colour expression.
They personalise human colour palettes and identify which reflecting colours, tones and contrasts create harmony and which create discord.
Like all colorDNA theory, the process to determine a person’s colour characteristic qualities is set up for every human colour combination, young and old.
The majority of the world’s population is found across Asia and Africa, and over many generations each race of people who live in a local area have developed the same or similar colour characteristic qualities.
Human colour characteristic variations, beyond Asia and Africa – lighter coloured hair and eyes – have, for the most part, stemmed from central and northern Europe.
Through migration and the development of the Western world, and the evolution of so many different ethnicities, natural selection has created a world population filled with every human colour combination imaginable.
However, the majority of the world’s population and colouring remains through Asia and Africa.
