I think the red one is like being in love with someone and one of the others, don't remember which one, is love you as a friend and then there's one that's "love you as a goat", been a long time since I learnt what they meant tho so I don't remember all of them

They're just colored hearts... I don't think they have a meaning behind them.

it's up for the user of the colored hearts to decide

To boldly go where no emoji has gone before.
