I promise this isn't really about videogames. I mean, a little, but not much.

The black and pink versions of the DS Lite are being released in the US quite soon. 'Onyx' and 'Coral Pink', I should say. Now, in Japan they called it 'Noble Pink'. Why the switch?

Does pink mean something other than 'feminine' in Japan? Is it associated with the nobility there, as blue and purple are to the anglosphere? Are Japanese more likely to respond well to concepts of nobility and class structure? Does Nintendo fear we will take up arms against their nobles and overthrow them, establishing 'Casteless Pink' and 'Merit-based Salmon' DSes?
