It is important to acknowledge colour deficiencies and cater for them if possible as it is common in individuals. The deficiency is mostly inherited by individuals although factors as serious injuries and illnesses could also cause this. The term colour deficiency is often mistake for some form of visual impairment, this is inaccurate as those with the deficiency can have good eyesight they just cannot define the actual shades and colour of objects. Surprisingly the condition can be so minimal that an individual might not even know they have the condition, it seems that only more obvious or extreme cases can define having it.
Here I will research the various types of colour deficiencies, I will also look at various websites and see how and if they have catered for those individuals.
Types of Colour Deficiencies
Red/Green:
- Most common type
- Struggle to see one of both shades or object
- Colours such as pink will be hard to define as he user cannot detect the red ratio within the shade
- Deuteranomaly is the lack of ability to define the colour green, this is very easily inherited within the X chromosome
Blue/Yellow:
- Less common type of colour deficiency (blue is very rare)
- Individuals struggle to define blue/yellow/green/violet shades in objects
Monochrome:
- Individuals can only define various shades of grey including black and white
- Very rare type of deficiency
- It causes a lot of problems within their day to day lives
