@JDPorter: My comment was actually a joke. I think that hex triplets probably even predate the first CSS standard. That being said, the kata test cases cannot get changed after 500 warriors have passed the tests.
3 digit color codes go back to 2001, though: http://www.w3.org/TR/2001/WD-css3-color-20010305. I guess I wouldn't be surprised to see individual browsers with poor support, though.
Probably a "mandatory legacy browser". ;)
If this is for css, shouldn't '#111' be acceptable as well?
