Is 'red rag' always used with 'to a bull'?

What's the difference between a 'red rag' and a 'red flag'?

A 'red flag' is a signal or sign of danger, a problem, or a warning ('His absenteeism was a red flag for the manager'). A 'red rag' is specifically something that provokes or incites anger or a furious reaction ('Her criticism was a red rag to him').
