Are idias lips naturally blue?

Excuse me, but I couldn't help but notice the mention of "idias lips" being naturally blue in the paragraph. Could you please clarify what you meant by that? As I understand, the term "idias" is not a commonly recognized term in the context of biology or anatomy. Are you referring to a specific species, condition, or perhaps a typo? And furthermore, are there any known animals or creatures with naturally blue lips? I'm genuinely curious about this and would appreciate your insight.
