Why is the color pink often associated with love?

Question

are there other colors that are often associated with emotions?

Answer 1

Yeah.

Blue=sadness

Green= jealousy

Yellow=happiness

As for pink, I do not know why it is associated with love. Maybe because some flowers are pink and flowers are known for having a "soft" and feminine touch about them or simply because the color pink itself is soft, like love :)

Answer 2

Because it {pink} is soft.......fuzzy, warm and sweet.
