The colour of water. We have pencil crayons and paint chips named after it.

We admire it when we arrive and praise it for being "that" colour — that colour being determined by your geography. Mediterranean Blue might be your favourite blue in all the world while you are in Santorini, but then forgotten and overshadowed by Caribbean Blue when you are swimming in it in Aruba.

We marvel when it mirrors and absorbs all of the colours of a sky and its surroundings. Sometimes it's a peacock sky with puffy white clouds suspended. Other times it's a quilt of stunning sunset pink.

In our mind's eye, water is a colour.

But isn't it crazy that no matter what landscape you're in... when you pick it up in your hand, the colour of water is always the same. There is no pencil crayon called "Clear".

And then I wonder, if I am made of 75% water as told in science class and countless issues of Shape magazine... what colour am I?
