We rely on colour vision to understand all sorts of information e.g. colour coding in graphs, traffic signals, medication, and of a huge number of other things. So what is the impact on someone who is colour blind trying to make sense of, say, the line graph in your presentation? I'm really interested in finding out, so whether you are colour blind or have normal colour vision, you can take the survey here https://cityss.az1.qualtrics.com/SE/?SID=SV_br4haKicXvSAQ1n

Thanks!
