Completely agree with antisocial. Also, would like to point out the fact that, we can't really define things like love, whether it be through colour, words, or even gestures. Each person has their own way of feeling or seeing it, so it'd different for every1.
For me, love is...yellow. Not just Yellow by Coldplay, but also because, I feel loved, safe and warm when the heat from the sun falls on my face. That's my calmest state and always has been.
It's ironic that I hate the colour.
