QCB - test
Here is a quick test to see whether you can discern indeed 
all colours in a 'difficult' environment. The game is simple.
When scrolling down you add all the numbers. At the end
of all images the result will be revealed.
In addition all numbers together should have been summed
up as 207.
What if you have a different result? Well, don't panic.
There are a variety of options left. At least you could try to
recalculate. You might use a calculator: just click here.
If still the result differs, this indeed could mean that for
some reason you missed a number. One of these reasons 
could be that you might have a different colour vision. In
that situation you missed a number because you only saw
some dots or something else. In that case it is advised to
visit an oculist than to investigate what type of colour vision
you have.
