Why is NTSC color carrier frequency 3.57954545 MHz and not some other number that can be remembered easily?

Hello guys. I am back after a long break. Now I will continue to tell a little more about NTSC before I start writing blogs on the actual Game Console implementation on LPC1768. I would suggest you to read the previous post before reading this one for better understanding.

I mentioned that the NTSC color carrier frequency is 3.57954545 MHz. If I want to create a game console for NTSC TV then I need to generate this frequency and use it as the color carrier. But why is 3.57954545 MHz chosen as the carrier and not some other frequency which can be easily remembered or generated?
