Dear CSS folks, I am writing to give you my opinion about color notation for as a User Interface consultant and Human Factors Professional (I am a Fellow of the Human Factors and Ergonomics Society and a Certified Human Factors Professional). CSS should include HSL. To use RGB makes _no_ sense from a user's perspective. From a UI perspective, a UI that people find difficult to use is a poor UI. RGB is a poor UI. It is hard to learn and hard to use. RGB notation is also a poor notation from a usability point of view: when confronted with a color in RGB notation, it is hard to determine what color it is, and if you want to encode a color, it is next to impossible to do it without the use of a tool that does it for you. While not perfect, HSL goes a long way to making colors more easily expressible, while not increasing the work greatly for implementers. HSL would help make the Web a more human-oriented place. Since we are all increasingly dependent on the Web, this is the right thing to do. Thank you for noting this perspective. I hope you will make this change. Sincerely, --Susan --------------- Susan M.
