ABOUT DALTONISM

Color blindness is the common denomination to a congenital alteration related to the incapability to distinguish several colors of the spectrum due to a visual deficiency.
There are several types of colorblindness. The rarest of which is Monochromacy, which affects the perception of every color, resulting in a black and white or grey shaded vision. The most common type of color blindness is Trichromacy which results in skewed interpretation of different shades of color.
While a person with a normal vision may see up to 30.000 colors, a colorblind has his visual capability limited to 500 to 800 colors.

Diferent kinds of daltonism:

Dichromacy
Trichromacy
Monochromacy

The vast majority of color blind people have a normal vision relatively to the other characteristics which compose it, even though the deficiency hampers, or even makes it impossible for those afflicted to perform certain everyday social and professional tasks.
Color blindness affects approximately 10% of the world's population and it's a handicap usually genetic in origin associated to a flaw in the X chromosome. Because of this, 98% of color blind people are male. Women can be born color blind only if both parents are similarly afflicted.

The first symptoms of colorblindness appear during school-age.

Afterwards, the colorblind "sees" a wide range of professional occupations being forbidden to them, such as pilots, navigation, graphical industry, chemical industry, geology, archeology, activitis connected to the computers or financial areas, decoration and fashion, among others.

Buying clothes always implies the assistance of others.

Many other daily situations force the colorblind to request the assistance of others: maps interpretation, traffic lights, the right understanding of the flags at a beach, choosing and identifying any product or service in which color is a main factor for decision.
