I bought some of the "purple" 2x3x4mm LEDs off of eBay from a seller in Hong Kong and they're definitely more magenta in color. It's fine with me, but I haven't seen any truly purple/UV 2x3x4mm LEDs yet. When I asked if they had any true purple, they said there weren't any, at least not in 2x3x4mm. I could be wrong though since I bought them some time ago.
