Structural formula has a grey O?
Hey, I had a question. I found a structural formula in a book with a gray O, the rest is all printed in black.
Personally, I've never seen anything like this before, so I wanted to ask, if anyone knows what it means, can someone explain to me?
Thank you for your help.

Is that a copy? Perhaps in the context the oxygen atom is important that it has been highlighted red and then gray in the repro? If there’s nothing in the text, I’d ignore it.
It’s not a copy, and there’s nothing left in the text, just maybe it’s something important.
Don’t think so. I looked at it again, it’s a normal carbonyl group. Perhaps the author has the image from another medium and the file actually had a highlighted O.
It could be thanks for the answer
Looks like misprint/copy.
I don’t think it’s because the CH3 is on the same height and is black.
I’m not the right person for questions of faith.
You’re probably better than me.
