Which is the best solution?

A. It doesn’t rely on color alone

Photo (marked A.) of labels moved adjacent to computer ports so there is a direct relationship between port and label. It depicts the best solution. Photo (marked B.) of computer ports color coded red and green to match the color of the mouse and keyboard labels. It does not depict the best solution.


  • The reason it is better is due to the accessibility of the solution.
  • Just one example of how usability and accessibility are related.
  • Want product usable for everyone, not just people who are not RG color blind.
  • Really, the best solution would also have Braille with the label adjacent to the port.
