Why do we use three character hex color codes for safe colors?
We use three character hex color codes of browser safe colors, for example #F4E means #FF44EE, each one is repeated twice to give a 6 character code. Why are these browser safe, can't browsers handle 6 digit color codes accurately these days? I notice sometimes a JPG sometimes shows a different color when viewed than it did in the editor, is that to do with this?
