Tannins are derived from plants and produce the color of a typical cup of tea. The pigments occur in roots, leaves, seeds, and bark and leach into water producing yellow, brown, or black tones. They can even be observed from space.

According to NASA, new satellite imagery shows a shallow inlet in Canada's James Bay with tannin-stained river waters and sea water mix. The frest water is draining from bogs, meadows, and soils in the northern borial forests and combines with sea water in the bay. The colored plumes and intricate patterns produced around islands illustrate tidal direction and how wind affects the flow of the two fluids.


The fluids can also be stunningly beautiful almost like an abstract painting on a gallery wall.
