I may be confused, but not about this. There should not be a red wire on a 220V Single phase circuit. Switching the two hot leads on the line side of a 220V single phase circuit should not do ANYTHING at all.
There should be a red wire, and a black wire, and a white wire, and hopefully a green wire, on a 220V 3 phase circuit. Switching any two of the red/black/white leads WILL reverse the motor direction.
Perhaps Ken you were in the motor control block and rewired the start circuit relative to the run circuit? That would change direction on a reversible motor and might involve a white and red wire depending on your motor.

Home wiring color code is pretty simple white is neutral, may be missing in a 240 circuit, bare or green is ground. All other colors are hot. Normally hot is black and maybe red or blue.
three phase... green or bare is ground. all other wires are hot. normally all just black wires going to the motor.

My Davis and wells table saw has a Dayton motor single phase that can be wired to run Cw or Ccw.
In fact it was running backwards with a very cheap miter saw blade on it when I rescued it from a Life of cutting MDF for signs.
Im pretty sure the person wasn't thrilled about the saw running that way.Looking at the bright side of things at least the dust was shooting away from the operator.
Heres a diagram that proves it.

Some trades use regular blades installed backwards - example is vinyl siding installers. May work on mdf also. Once saw high temperature, refractory round fire brick shapes reduced in diameter by turning with the square back end of a tool bit. Sharpened end wouldn't touch it

Some where you had a phase reversal. Was there a power outage or work recently done?
if you have 220 3 phase then there is no run or start capacitor turn of the power and switch any two leads on the load side of the contractor.
That should take care of the motor reversal

Lee,
Post #21, Member Kelly Hanna was given a saw and has the same problem.
