‘To see red’ means ‘to become very angry’, like a bull seeing a red flag (or so it is believed).

Similar idioms:

If you ‘lose your rag’, you get very angry and start shouting.

If something is ‘like a red rag (to a bull)’, it infuriates you (it makes you very angry).

Conchita, I would avoid using any idiom about anger or bad moods if it contains the word "rag". They are usually an analogy to menstruation, and they can be very vulgar.

Oops! Thank you very much for that, Jamie! I had absolutely no idea. So, no expressions with the word ‘rag’ in an angry context then, but ‘putting your glad rags on’ is still OK, I hope? Now your comment will pop up in my mind every time I sing the “Rock Around the Clock”! See what you’ve done?

"Glad rags" is okay. Don't worry.
