Color Brewer provides a list of symbology sets that are color blind safe; allowing a user to change the number of data classes and type of data being displayed in a map. While there is an ArcScripts downloadable file to incorporate the Color Brewer symbology sets, our IT department does not allow external downloads of any kind to our local machines.
My coworkers and I currently set symbology based on the RGB colors provided by Color Brewer to each individual level. When my coworkers ask to see other options I have to make copies of the datasets and change their symbology individually and turn on/off layers to avoid losing the symbology of the original dataset.
This is a requirement of my program, and other programs that are under Federal grants, as accessibility is now a Federal standard when working under any Federal grant.
