colour vision deficiency, orienteering, map reading problems

Orienteers with colour vision deficiency may face different issues when reading a colour coded orienteering map. These issues can be compounded when competition maps are not printed to specification in respect to correct colour and print quality. ISOM 2017 improved recognition of symbols without relying on colour by introduction of specific symbols per colour. However further work is still needed in other areas. The purpose of this contribution is to provide a brief introduction of possible solutions such as improving colour settings or changes to the symbols to aid in identifying them.
