laugh yourself pink meaning?

What does this sentence mean?

You would have laughed yourself pink if he’d told you earlier.

Thanks.

It's not an expression I have come across. It probably means that the person would have been extremely amused.

I know these expressions:

laugh yourself silly
laught till you cry
laugh your head off
laugh like a drain.

There are almost certainly others.
