Do girls have different meanings for different heart colors?

If I send a girl a good night text, and she hearts the message but then say goodnight with and sends a yellow heart instead of a red one, is it for a reason.

She likes sending all sorts of heart colors. Sometimes they are white, most times they are pink growing hearts or red hearts. On a few occasions they’ve been green hearts.
