Everyone keeps talking about the "deleted" and "magenta" thread...
Can someone let me in on the joke? E feel like magenta is a reference to ortho vs pan film?
A member, presumably during one of those interminable technical discussions, argued that magenta is not a colour. He certainly did not mean there isn't a colour that people call magenta. He was certainly talking about primary colours*, colour theory, and something like that. Nominalistic quarrels are uninteresting in any case. This particular quarrel was probably originated by one of those long thread where everything becomes object for specious distinctions. It's, again, "human behaviour".
* magenta is a primary colour in subtractive synthesis so he must have actually meant something different.
