Adam, You've got an interesting challenge on your hands! Have you considered using other visual cues to indicate differences? - Outline type - Fill patterns - Labels I know you're probably doing this in desktop GIS, but I find this Javascript library really beautiful. Maybe it can serve as an inspiration. https://riccardoscalco.github.io/textures/ Good luck! Stephen Smith GIS Project Supervisor Vermont Agency of Transportation From: Northeast Arc Users Group [mailto:[log in to unmask]] On Behalf Of Adam Kurowski Sent: Wednesday, May 11, 2016 12:33 PM To: [log in to unmask] Subject: color blind friendly mapping The Project: To replace a black and white, paper zoning map that is designed with hatch, line, and marker symbols with a colored version made with GIS that easy to keep updated. The Problem: One of the main staff members who will use the map is color blind. The map would require 10+ colors and the color blind friendly color ramps, can't handle that many variations in relation to this person's type of color blind. I have looked at many resources<https://blogs.esri.com/esri/arcgis/2011/02/23/color-tools-for-map-makers/> and they have helped, but the number of zones and overlays still make the map hard to distinguish for the color blind person. I would love to make one all-inclusive product, but that may not be possible. The Questions: 1. Does any have experience or advice to help make this municipal zoning map color blind friendly? 2. Can anyone offer a creative solution, simple or high-tech, that could help this one staff member access the zoning information in another manner? 2a. Is that an acceptable alternative and is it maintainable? 3. Should I follow the KISS rules and just convert the map to GIS and stick with a black and white hatch, line, symbol map? Thanks! I'll compile and share the results.
