    User Interface versus Color Vision Deficiency

    Approximately 1 in 170 women and 1 in 12 men have a decreased ability to see color. Color blindness makes it difficult or impossible for a person to engage in certain occupations; this however had no impact on the success of: Bill Clinton, Keanu Reeves, Mark Zuckerberg, Prins William and many others having similar Color Vision Deficiencies.

    The effectiveness of a web-page or application does not always consider that over 200 million people across the globe have a decreased ability to see color differences. The most common form is Deuteranopia (green-blindness). Yet, many cartographers, designers and application developers don't factor this into their work. As an example, people with Deuteranopia detect traffic jams from Google or TomTom websites differently from people with normal sight.

    Have a look at the image below:

    If the image below is like the one above, you might have some form of a Color Vision Deficiency.


    Here's another example:

    If the image below is like the one above, you might have some form of a Color Vision Deficiency.


    Drawing and conveying relevant or important information in different ways such as using wider line, shaded, striped or hashed fills is highly appreciated by those people who would otherwise miss the message.

    If you wish to test color blindness there are multiple apps or software tools available.

    Some examples:  

    • App: Sim Daltonism,
    • Software tool: Iris
    • Website: Coblis

    Many people don't know it, but Location Intelligence, Analytics, Infrastructure Management and Georeferencing solutions often force people with blind color deviations, to use a specific app to detect color. Example Color Blind Pal

    Example:

    Highly Automated cars do benefit from using high quality maps, these HD Maps are marked in Red in the image below.

    In case you are not one of these 200 million people with one of the most well-known forms of color blindness, here's how those with different conditions perceive the colors you may take for granted:

                Normal View                 Protanopia               Deuteranopia                  Tritanopia
                                                  Red Blindness           Green Blindness           Blue Blindness

              *Countries marked in red have the HD Map ideally used for highly automated driving.

    App developers need to understand their audience, including those with a Color Vision Deficiency.

    ColorBrewer is a great resource for cartographers and developers.  It offers color combination options that take into account those with color vision deficiencies.

    I second this nomination Cecily.  ColorBrewer is a huge help whenever I've had to create maps in the past.  It is very easy to work with.
