Colour-blind in Kitzbühel

The colour-coding of ski trails, according to level of difficulty, is generally sensible and familiar. "Green" for beginner runs, "blue" for intermediate runs, and "black" for advanced runs (with some variations — e.g, the addition of "yellow" for super-easy runs, and of "double black" for expert / semi-suicidal runs). An international standard — or so I thought. But not here in Kitzbühel. Apparently, the Austrian way is to mark the trails "blue" for beginner runs, "red" for intermediate runs, and (thankfully still) "black" for advanced runs. Extremely confusing, and contrary to what I've now become intimately familiar with, over my several years of Aussie skiing. Argh!
