"In the pink" is an expression meaning: healthy (GENKI). It comes from the pink color of healthy skin. It can also mean "financially healthy" (rich).
For example: He's in the pink since he got that new job.
This blog is mainly to explain a different English language expression every day. Sometimes I post other stuff. I also have a YouTube channel which is mostly about computer software: https://www.youtube.com/englishspacedog
