Yellow flowers have long been regarded as the colour that you would send to friends or to someone to let them know that you're just friends. Also as yellow is associated with the colour gold it also symbolises provision and sustenance. Pink - Appreciation, Gratitude, Sympathy. Often the colour favoured by young girls.
