There aren’t actually any specific “primary colors”. You can use many different trios or color as “primary colors”. RGB is the one that most directly represents what we see, since it’s the trio of colors that our eyes react to, but you could use yellow instead of green or Cyan Magenta and Yellow or other color systems.

As long as they combine right, it works.
