Colour Vision Deficiency: is it a problem and if so whose problem is it?

Colour Vision Deficiency (CVD), or colour blindness, refers to the inability to distinguish different shades of colour.  The majority of people who suffer from CVD do see colours, but they have difficulty in distinguishing certain shades of colours.  This is most commonly manifested with shades of red and green pairings and also with shades of blue and yellow pairings which can result in a difficulty in identifying shapes and sizes.

With the technological revolution in our modern world, we receive vast amounts of information on a daily basis.  We are expected to interpret this given information as the authors of the information intended.  Here lies the difficulty for the Colour Vision Deficient (CVDt), unless careful selection of colours and shapes are used by the authors, then there is a high probability that the intended information is misunderstood which could cause severe problems to the CVDt.  So whose problem is it?
