Hi Adam and everyone who responded to his question. Would it be OK if I tried to synthesize the question and responses into a short article? I think I can go back to the NEARC-L archives to figure out who contributed what so I can give attribution. It was a great, quick lesson in cartography for me and I would like to post it on our VCGI Blog if possible. If anyone who contributed objects to being identified, just let me know directly.

Thanks
Leslie

Thank you all for the thoughtful responses.  This being my first attempt to make a color blind friendly map, I didn't realize how many would already have experience.  Attached are the responses I received.

In general, there are some good website tools out there.  I believe I will need to learn more about the needs of the color blind person and map with some combo of colors, markers/hatches, and labels.  The level of effort may be greater, but reaching a key audience is the reward.

Mappy Friday!

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.
Adam
