Water may appear clear in small amounts, but has a blue tint.

Detailed Description

"Pure" water may look clear, but it actually has a blue tint

An indoor swimming pool appears blue from above. as light reflecting from the bottom of the pool travels through enough water that its red component is absorbed. The same water in a smaller bucket looks only slightly blue, and observing the water at close range makes it appear colourless to the human eye.
