Colour blindness is a condition in which the ability to distinguish specific range of colours is average or below normal. A person suffering from colour blindness has trouble seeing red, green, blue, or a combination.
A person’s ability to see some combination of colours is rarely lost (monochromacy). Many people believe that only black and white colors are caught in a person suffering from Full(monochromacy) type.
If employees in your organisation are routinely making colour decisions based on what they can see, it may be wise to have their colour vision tested periodically. Colour Vision may be deficient from birth with a hereditary cause but can also change during someone’s lifetime as it is susceptible to being affected by the age and health of the person as well as substances, they ingest such as caffeine and alcohol or medication.
