Hagrid's real intention, however, was to talk to Harry away from the rest of the class. He waited until everyone else had set off with their skrewts, then turned to Harry and said, very seriously, "So – yer competin', Harry. In the tournament. School champion."
“One of the champions,” Harry corrected him.
Hagrid's beetle-black eyes looked very anxious under his wild eyebrows.
(p294, Harry Potter 4, US edition)
There’s not so many varieties in eye color in people of my country and therefore in novels, except for in figurative expressions. This might be why eye-color descriptions draw my attention.
'Beetle-black eyes', not just black, is sometimes referred in the story as if it is Hagrid's trademark
I searched the Net for beetle-black and had an impression that the color is bright and pure black. Now I'm just wondering it might be connected to Hagrid's character and mentioned when the writer wants to emphasize his pureness. However, this is just a wild guess because I don't know English speaking people commonly connect eye color and people’s character, just like astrology.
I'd like to know if 'beetle-black eyes' is related to Hagrid's character. I'd be happy if you could help me!
