Nice colours for the 'darker' eastern orientals there, Prof.! Tibetans and south eastern asians (including South China) are spot on, as far as I can see from the pics. Maybe even Mongols.
I think I would prefer a tone slightly lighter for east-eastern skin (Korean, Japanese, North Chinese and the likes), though. And also for women.
Anyone got some good 3-colour series they'd like to share?
