Standard definition CRT TVs make the pitch others have stated at
15.734 KHz.

It depends what that 'standard' is! Most of the world do not use NTSC 60.

OK, 625/50 PAL runs 15.625KHz so it still applies.

from Wikipedia:

"The 4.43361875 MHz frequency of the colour carrier is a result of
283.75 colour clock cycles per line plus a 25 Hz offset to avoid
interferences. Since the line frequency is 15625 Hz, the colour
carrier frequency calculates as follows: 4.43361875 MHz = 283.75 *
15625 Hz + 25 Hz."
