I've came across this kanji when reading this fantasy light novel, 黒【こく】瞳【どう】 (the furigana was also in the book), but I can't seem to find the meaning.
I've searched for it in both english and japanese but could not find it.
I know "黒 means black" and "瞳 means pupil", So maybe I'm supposed to think that this means "black pupil"?! But google image only shows black pupils/eyes if I type 黒い瞳.
For context, the following line contains that word in the book (where a girl's appearence is being described):
From that whole line, the only thing I can't understand is 「高い知性を窺わせる黒瞳」... Black eyes that make you presume she's super intelligent?
