WHY ColorADD
COMUNICATION – “...it´s all about colours”
Colours are determinant in communication. It is known that individuals access 70% faster the communicated information when colours are used.

Red and Green are the most relevant colours used in Global Communication, including a wide range of services, traffic guidance, geographic maps, on/off buttons and infinitive more segments and situations worldwide.

Red and Green are the colours most commonly related in colorblindness or color confusion. Colorblind individuals have daily challenges that induce psychological and social discomfort. Feelings range from sense of dependence, to difficulties in social integrating, psychological insecurity, bad school performance or unsatisfactory professional integration.

DALTONISM
Color blindness or color vision deficiency is the decreased ability to perceive differences between some of the colours that others can distinguish. The condition is often called daltonism, named after John Dalton, the scientist who first described the pathology. It is accepted that 10% of the male population is colorblind in a variable extent.

Colorblindness is a condition known from Antiquity but it was in the XVIII century that it was first described by John Dalton, a British physic. He was colorblind.

In the XIX century, Hermann Von Helmholtz proposes a theory describing the organic mechanism responsible for the colorblind state in line with the studies of Thomas Young. The Young-Helmholtz theory, argue that the retina had specialized cells, named Cones, that were responsible for the color perception and the malfunction of these cells would cause colorblindness.

Cones are less sensitive to light than the other cells in the retina but allow the perception of color. They are also able to perceive finer detail and more rapid changes in images, because their response times to stimuli is faster than those of rods.

Humans usually have three kinds of cones with different photoreceptivee proteins, which have different response curves and thus respond to variation in color in different ways. Changes in the protein composition of Cones, implies different colorblind states.

The condition of colorblindness has a genetic origin related with X chromosome.

The first symptoms are detected early at school age normally related with difficulties or confusion acknowledging the different colours and already at this time the feel of social inadequacy is initiated, enhanced by the tease of the colleagues. At a later age, numerous professional areas are forbidden, namely, aircraft and ship piloting, the graphic industry, the chemic industry, the geology, archaeology, IT, among numerous others.

In time constrains are enhanced as the complexity of life increases: the scope of professional possibilities decreases, the personal fulfilment decreases and the sense of non-integrated increases.
