Even in Best Buy Shanghai it means blue. Check this out:
All in blue. Also, I'd like to point out that they're probably selling fireworks at this best buy, or at least that's what this picture has led me to believe. Well I can guarantee you that they had to outsource to bring in the fireworks department, but they are still wearing blue... despite the obvious fact that any fireworks department SHOULD BE red. But Best Buy Shanghai knows their brand and keeps it. They won't let no stupid outsourcing let their brand become anything but blue polos and khakis.
I'm actually really curious why they all have fireworks. A firework in the television section could lead to one hell of a mess. This just seems like a bad idea. But at least they look good doing it.
