It seems to me like it'd have a Chinese-like pronunciation, that is Yin Min.
Tangentially, as a non-native speaker, "ultramarine" has a fairly similar amount of information encoded in the name as "Yinmn"--pretty much zero. So, the two names ("ultramarine" vs "yinmn") are pretty much equivalent to eme, personally.
Goes to show that naming things "properly" is difficult (I suspect it's impossible actually).
