Quality of color coding in maps for color deficient observers

Anne Kristin Kvitle, Marius Pedersen, Peter Nussbaum
2016 IS&T International Symposium on Electronic Imaging Science and Technology  
For a color deficient observer, the quality of a map or other information design may be defined as the ability to extract features.  ...  As color appearance is affected by the size of the stimuli, the task of discriminate colors may be even more difficult for a color vision deficient observer.  ...  One major problem with simulations is that they operate more like a guideline for a designer with normal color vision.  ...
