According to the talk (which derived from real case studies), we (in Portugal) have a population of 10% with one of the several variations of color blindness. In my 1st job (on a small IT department), i had a colleague (from the electronics department) which had a variation of it. Dealing with electronics, means in some form, dealing with color codes, like colored cables, LED's and other instruments, which means he had difficulties dealing with it. It was not very known, and i understood why after the talk, in which there seems to be a stigma on color blinded about them being recognized as such. So, although not perfect, it made sense to me as solution to allow people being independent. I live in front of one of the metro stations, in which this code is already applied (like in many other countries, our metro rails are identified by a letter and a color). In our hospital urgencies, we use a braced color to identify the urgency of the patient. Green, blue, yellow, IIRC. Like real blindness, there may not be cure, but there are solutions to improve a person's life quality, even if it just helping a [color blinded] father being able to pick baby clothes for his son, not "daughter" :-)
