* "Man" is a tricky word to rhyme: It has a very common sound that's hard to match with other words.
* "Primary color" is a compound noun: This makes it even harder to find a single word that rhymes.
Here are some options, depending on what you're looking for:
* Near rhyme: You could use a word that has a similar sound but isn't a perfect rhyme, like "span" or "plan."
* Playful approach: You could create a made-up word, like "primary color fan" or "primary color clan."
Ultimately, the best rhyming word pair will depend on the context and the tone of your writing.
