What people say when I tell them I'm colorblind

They continue asking what color things are until I get one wrong. Then they laugh and tell everyone within ear-shot how I I think this thing is a different color than what it is. Apparently color blindness is freakin' hilarious.

I see what you did there.

"That's interesting" isn't a question.

You forgot "what does this look like to you?"
I never know how to answer
