How can I call an object GREEN when I don't see GREEN, but how do I know what colour GREEN is when I call another object GREEN? Can you see what I see ?"               Dennis R. Overton


Every day we are faced with decisions that the non colour blind of this world take for granted! But it is not the colour of our world! (See what we see - Coloured Links Page)
Our sunrises and sunsets are not interesting; Our rainbows are plain; Our fruit is not ripe; Our meat is not cooked; Our clothes do not go together; Our paint charts are a blur; Our printer/camera batteries are never low; Where are the flowers on the Christmas bush? We all have a box of 24 different coloured pencils we never use? Red and green dot clearance sales are great; Travel route coding and signs are a waist of time; We can not even see when we are sun burnt; I could go on, yet today, children and adults are still being told, when diagnosed with colour blindness, you will adapt and that's it!
The colour blind do not know any difference in the colours that they are seeing...they were born with it! Yet the non colour blind of this world assume that we all see the same or no colours. SORRY!
Colour blindness can be like watching television with the red and green knobs broken!


Defective colour vision is a complex subject and even today scientist do not all fully agree on the theory of colour vision and subsequent defects. You are directed to the help page for further study. However they all agree that colour defective vision is usually hereditary (It can happen also by illness, accident and old age) and is passed by the defective X linked sex chromosome from the male to female carrier and then 50/50 chance to the male etc;

An interesting fact is that, it is rare (1:200) for women to have colour defective vision, yet, 14-18% of all  women (Australian 1.8 Million) carry the defective gene and are completely ignorant of the fact!

A simple overview of colour vision is that light given off by an object enters the eye through transparent tissues turning it into an electro-chemical signal, then sending it via the nerves to the brain, that interprets it into visual image. The eye has many nerves, cells and cones which interpret the colour signals and some of these may be missing or malfunctioning and thus interfere with normal colour perception. Therefore we have different classifications of colour blindness and even a variance within each classification. But how do we know what colour green should look like? (contact us for pamphlets)
