Originally we thought we should choose to create a visualisation around ‘how’ a colourblind person would see the world day to day by comparing photoshopped images. However, we realised that this is a fairly common visualisation to find via a simple google search. Instead we chose to visualise the statistics around the prevalence of colourblindness, and we were shocked at how common it is.
The core of this assessment is to make the invisible, visible. Our research on colourblindness led us to this website provided an abundance of statistics from which we could construct our visualisation. The form which we thought our visualisation aligned with was a point of debate amongst our group. On one hand, our visualisation does represent scientific data. However we concluded that the form concerning the visualisation of science within the public sphere is more suited, as you do not need a scientific understanding to engage with our visualisation.
We chose this form specifically so that our visualisation would act as a point of engagement but also a medium through which we would inform the public about awareness of this condition- which effects more people than expected.

8% of men world wide are colour blind, to put this into context colourblindawareness,org uses an analogy : At an all-boys school with 1000 pupils would have approximately 100 colour deficient students. 12-13 would be deuteranopes, 12-13 would be protanopes, 12-13 would have a form of protanomaly and 62 would have a form of deuteranomaly.

This analogy does not explain that these percentages focus on the two different types of colour blindness.  Those with deuteranomaly and proanomaly have Anomalous Trichromacy, where the colour receptors are damaged and Deuternopes and Protanopes have a form of Dichromacy, in which a colour receptor is missing . So our diagram includes this information to avoid confusion.

100 in 1000 are effected.

About 25% will suffer from Dichromacy and about 75% will suffer from Anomalous Trichomacy

The percentages of those with Anomalous Trichomacy are:

62 would have a form of deuteranomaly (can see blue)

12-13 would have a form of protanomaly (reds can be mistaken for black)

The percentages of those who suffer from dichromacy are:

12-13 would be deuteranopes (can confuse blues with purples),

12-13 would be protanopes (everything seems red)

We chose to represent the analogy rather than raw statistics as the numbers were simplified but the scale and concept was still difficult to understand. To make this image we thought it would be best to represent the statistics with male figures as colour blindness is most prevalent in men. To better represent the sub divisions of colour blindness we chose to animate the transition of our images rather than try to make it all one image as there was a lot of information to visualize.

Unfortunately, as we made it ourselves in photoshop and prezi, scale was sacrificed so that the image was more representational.

When researching, designing and constructing our visualisation we came across a few issues, which placed limitations upon our visualisation. Firstly, as a result of extensive research we were left with an abundance of information and statistics- which made narrowing down what we wanted to include difficult. We though we had done well when we designed our first visualization, which included far more detailed statistics that we thought were necessary to increase the information our visualization communicated. To test the impact of our visualisation we showed it to a friend and received feedback concerning our visualisations complexity. It was then, that we decided to narrow it down even further by only focusing on the prevalence and the variations colour blindness. By simplifying the information we avoided confusion around that statistics, and stuck to our original goal of awareness as opposed to overloading information.
