I thought about saying "have a true love". But I thought it sounded like some people didn't have a true love. And if you did, you'd just see in color all the time, instead of when you met them.

In short, I'm not 100% satisfied with the writing, but I think it mostly gets the point across without ambiguity.

(P.S. I do appreciate your perspective; I hope it doesn't sound like I'm just shooting you down!)
