I would have to say purple. Purple is a deep, intricate color with a variety of cool and warm shades, like love in some ways. People automatically vote red because red has been used so much to be associated with love, that i dont even know what the meaning behind it is.
i chose other colors because love can be represented in many different ways
red and orange and the like are for intensity and passion, but blue is also for the like as in deep intense love
green, which i like most, is for newness, and is the ins and outs the workings, the gears, the underlying current of love, the part that makes you get moths in your tummy that migrate to the bottom of your throat and render you speechless and breathless
white and black are harder to find because they are the person'd core, the soul, both reflect pieces of the mind, the deepness of it, the parts one must travel through to find
so for me i am green, white, and black...well and blue, and orange, and red...lol
