go blue

[akudash]

A friend asked me about go blue that her instructor said to her. I has found in this website, the definition is if you go blue, you are very cold indeed.

but it doesn't make sence. what happen was after her provided some sort of infomation to her instructor, then she said she was going to take an exam, and then Her instructor said, thanks and go blue.

I have googled it, but still can't get a proper definition. Is it some kind of new idiom in America? or she heard something else has same pronunciation?? plz help me out, thanks a lot.

The only way I can think of 'go blue' as an idiom is as either to show someone is cold, as you said, or meaning that someone can't breathe (during which they likely do turn blue-ish, and so it isn't really an idiom).

The only 'colour' idiom I can think of that relates to examinations is 'pass with flying colours' meaning 'pass with a high mark'.

But what the instructor said, or what your friend heard, I have no idea what it means in relation to examinations.

Are the school colors blue and something?

We say "Go Blue!" to mean you are cheering for a person from a school where the colors are blue and something. Michigan comes to mind.

You also say something like "Let's go, Red!" for a school where the colors are red and something else.

That's the only thing that makes sense to me.
