What looks better? Noctigon KR1 black, blue or gray?

Gents, GREY is DARK DARK BLUE.

I'm so happy I didn't get BK or BL

Impossible to pick. All nice.

Blue

Grey, which as id30209 said is some sort of dark greyish blue.

My first choice is always black, then gray, and then other colors.

I have a KR4 in grey and think it looks fantastic.
