nice, but orange and green are only distinguishable if you know the orientation. so the wrist tags used in the example are orange/green ambiguous (i think there might be some text below that provides a baseline, but it's very difficult to see in the photos and shouldn't be necessary).
it wouldn't be quite as pretty if it was asymmetric, but it would remove that problem and so be easier to use.
