Blue

It is irrevocably human to associate blue with water and to love it because of this bond.  After all, our survival depends on water, and to a subtler extent, so does our psychological sanity. In this respect, blue is the color at the core of our being, our sky, our oceans.  Blue can be playful; edging towards green in aquamarine, like the turquoise sea of the Caribbean.  Or melancholy, an emotion just as complicated as the many undertones of gray in a winter lake.  Blue is compelling, soulful and so inseparable from our world and ourselves that should all other colors disappear, blue would remain. True Blue. - l.o.d.
