Color is one quality of love - taste is another quality of love. Love from flowers has many manifestations just like love from humans may vary - the scent of a lover may vary with his mood and sexual preference or needs as well as with his/her spiritual maturity and purity of true love.
From the color of a girls face, lips or hands you may see her reaction to your love, from the scent of her natural skin you may smell the readiness to love, from the taste of her kiss you may taste the desire for love - like the ever changing color of a human aura when that person is in love ... or just like fruits taste or smell differently - so do humans smell and taste differently depending on their current state of emotional needs and emotional balance as well as spiritual maturity and purity.
