Binned maps from A) the interview, in which colour blind accessible colours were not considered (see Figure 1 D), and B) the survey map, in which a colour blind accessible colour scheme was used based on Color Brewer ( http://www.colorbrewer2.org , Brewer et al. 2013 ) (see Figure 2 B), viewed through an Adobe Photoshop® protanopia colour blindness filter, which shows how the image would appear to a person with protanopia-type (red-green) colour blindness. The issue of colour blindness was raised in interviews, which prompted the adaption of colour blind accessible colour schemes for the survey. The upper three classes have greater contrast, and are more discernible in B than in A.
