Although it wasn't really a problem to him in his day to day life, my Dad was colour blind, various shades of greens and browns all appeared to be the same hue to him. I'm not even sure that we (my mother and myself) realized that he was color blind until we were out one day looking for a new bathroom suite.

It was in those days when avocado was the must have color for the bathroom.. thank goodness those days are now a memory and white is back in fashion.. my mother had mentioned that she liked the avocado suite but my color blind dad told her that he had seen a nice coffee colored one. She scanned the showroom but couldn't see any sign of the coffee colored bathroom. It was no wonder, because the coffee colored suite was actually the avocado color that my mum wanted anyway!
Being color blind need not necessarily be a problem but it could be an obstacle to certain careers where good color vision is important.

What Is Color Blindness?
There are different types of color blindness
There are a number of different types of color blindness. The most common being red/green colour blindness, which involves confusion between the colors red and green. This type of color blindness is inherited through a faulty colour vision gene and has two forms:
- different shades of red appear dull and indistinct
- greens, oranges, pale reds and browns all appear to be the same hue, distinguished only by their intensity
Other, more rare, forms of colour blindness are:
- where blues and yellows can't be distinguished.
- All colours are seen in black and white.

The French optician Jean Jouannic offers an Online Multiple Choice Color Blindness Test based on 31 images. The images are either hidden signs and letters or a handful of colors which you have to match to a choice of color names. As colorblind people show great difficulties matching color names to colors, this is another appropriate method to test color vision. The test has some nice statistics when you have finished and tries to quantify your color blindness in detail.
