The color of water varies with the ambient conditions in which that water is present. While relatively small quantities of water appear to be colorless, pure water has a slight blue color that becomes deeper as the thickness of the observed sample increases. The hue of water is an intrinsic property and is caused by selective absorption and scattering of blue light. Dissolved elements or suspended impurities may give water a different color.
The intrinsic color of liquid water may be demonstrated by looking at a white light source through a long pipe that is filled with purified water and closed at both ends with a transparent window. The light cyan color is caused by weak absorption in the red part of the visible spectrum.[2]
Absorption intensity decreases markedly with each successive overtone, resulting in very weak absorption for the third overtone. For this reason, the pipe needs to have a length of a meter or more and the water must be purified by microfiltration to remove any particles that could produce Mie scattering.
Lakes and oceans appear cyan for several reasons. One is that the surface of the water reflects the color of the sky, which ranges from cyan to light azure. It is a common misconception that this reflection is the sole reason bodies of water appear cyan, though it can contribute. This contribution usually makes the body of water appear more a shade of azure rather than cyan depending on how bright the sky is. [5][6]Water in swimming pools with white-painted sides and bottom will appear cyan, even in indoor pools where there is no sky to be reflected. The deeper the pool, the more intense the cyan color becomes.[7]
Some of the light hitting the surface of ocean is reflected but most of it penetrates the water surface, interacting with water molecules and other substances in the water. Water molecules can vibrate in three different modes when they interact with light. The red, orange, and yellow wavelengths of light are absorbed so the remaining light seen is composed of green, cyan, and blue wavelengths. This is the main reason the ocean's color is cyan. The relative contribution of reflected skylight and the light scattered back from the depths is strongly dependent on observation angle.[8]
Relatively small amounts of regular ice appear white because plenty of air bubbles are present, and also because small quantities of water appear to be colorless. In glaciers, on the other hand, the pressure causes the air bubbles, trapped in the accumulated snow, to be squeezed out increasing the density of the created ice. Large quantities of water appear cyan, therefore a large piece of compressed ice, or a glacier, would also appear cyan.
Dissolved and particulate material in water can cause it to be appear more green, tan, brown, or red. For instance, dissolved organic compounds called tannins can result in dark brown colors, or algae floating in the water (particles) can impart a green color.[11] Color variations can be measured with reference to a standard color scale. Two examples of standard color scales for natural water bodies are the Forel-Ule scale and the Platinum-Cobalt scale. For example, slight discoloration is measured against the Platinum-Cobalt scale in Hazen units (HU).[12]
Water color can reveal physical, chemical and bacteriological conditions. In drinking water, green can indicate copper leaching from copper plumbing and can also represent algae growth. Blue can also indicate copper, or might be caused by syphoning of industrial cleaners in the tank of commodes, commonly known as backflowing. Reds can be signs of rust from iron pipes or airborne bacteria from lakes, etc. Black water can indicate growth of sulfur-reducing bacteria inside a hot water tank set to too low a temperature. This usually has a strong sulfur or rotten egg (H2S) odor and is easily corrected by draining the water heater and increasing the temperature to 49 C (120 F) or higher. The odor will always be in the hot water pipes if sulfate reducing bacteria are the cause and never in the cold water plumbing.[citation needed] Learning the water impurity indication color spectrum can make identifying and solving cosmetic, bacteriological and chemical problems easier.
The presence of color in water does not necessarily indicate that the water is not drinkable. Water with high water clarity is generally more cyan in color due to low concentrations of particles and/or dissolved substances. Color-causing particulate substances can be easily removed by filtration. Color-causing dissolved substances such as tannins are only toxic to animals in large concentration.[14]
Color from dissolved substances is not removed by typical water filters; however the use of coagulants may succeed in trapping the color-causing compounds within the resulting precipitate.[citation needed]Other factors can affect the color seen:
Various cultures divide the semantic field of colors differently from the English language usage and some do not distinguish between blue and green in the same way. An example is Welsh where glas can mean blue or green, or Vietnamese where xanh likewise can mean either. Conversely, in Russian and some other languages, there is no single word for blue, but rather different words for light blue (голубой, goluboy) and dark blue (синий, siniy).
The Ancient Greek poet Homer uses the epithet "wine-dark sea"; in addition, he also describes the sea as "grey". William Ewart Gladstone has suggested that this is due to the Ancient Greeks classifying colors primarily by luminosity rather than hue, while others believe Homer was color blind.[citation needed]
The Ancient Indian Wisdom of Veda consider life giving contributions of water a part of divine and recognize water as a primeval God Varuna; and the color of Varuna is described as blue. In the Gayatri associated with Varuna, the word "neela purusha" comes in second line which calls the water deity, the blue one.
Another question I have is the water color/clarity in the keys. I have seen in pictures brown looking water which is a huge no no for us. And other photos I've seen Caribbean like waters. A tropical paradise. A DREAM vacations. Where can we go that ensures we are surrounded by the Caribbean waters? Do we have to take a boat to get to that water and not right off of a beach?
True, the beaches in the Keys are not very good at all. And water color can vary from day to day depending on weather. But there is plenty of beautiful blue/green water surrounding the Keys. We like to visit some of the sandbars off of the Keys for nice water and a fun "beach" experience, but that requires a boat. We prefer for Key West overall, but everyone likes something different.
As mentioned above, the water color depends on weather. It can be beautiful and clear and many shades of blue and green, or when high winds churn up the water, it can be darker. The water is beautiful more often than not.
The Keys are very heavily advertising and some of the ads are disingenuous talking about pristine beaches and showing photos of a nearly empty road through the Keys. Take photos with a grain of salt. We do have off shore sandbars which are beautiful in good conditions, but you need a boat or to take an excursion to get there. Boating here is not easy due to shallow waters, protected seagrass beds and corals, so unless you are an experienced boater you will likely need to hire a guide.
You CAN find that brilliant blue water here. Today headed to Big Pine it wasn't so blue - but the sun was low. Coming home across the bridge the other way and it was brilliant blue. Both of us in the (ta && ta.queueForLoad ? ta.queueForLoad : function(f, g)document.addEventListener('DOMContentLoaded', f);)(function()ta.trackEventOnPage('postLinkInline', 'impression', 'postLinks-103875105', '');, 'log_autolink_impression');car said something about how crazy blue it was today.
Brown - if you're in an area with a lot of black mangrove nearby you can get the brown color at an outgoing tide. Has there been a lot of heavy wind? Again, won't be the brilliant blue. But there are days when you can see every blade of sea grass on the bottom or sand ripples. It can be just gorgeous.
The browns you sometimes see is where the water is very shallow and you can see the sea grass patches. The water itself is very clear. The colors are amazing different hues of blues, greens & browns. Yes, wind / clouds can dull it a bit, but with a whole week, you will likely see a lot of different "looks".
The color is not as apparent in the shallow water. This really intrigued me so I did a little research when I got home. One website said it is microscopic clay particles washed into the river from shale outcroppings during rain events. Other sites just said it is minerals. So the color is produced naturally, and it is beautiful.
Factors such as minerals, soil runoff and sediment and even algae can cause water to vary from its natural color of blue. The most common cause for water to change color is minerals. When a rock is weathered down over time, the minerals from the rock are dissolved and small pieces are released into the water causing different colors. Iron, manganese and calcium carbonate from limestone are all common minerals that can cause water to range in color from red and orange to green and blue.
Algal blooms are natural occurring overgrowths of algae caused by sunlight, slow water or nutrients. Pollution runoff from humans can also increase nutrients in the water and cause an algal bloom. Algae affect not only the health of a river but also the color. The color caused by algae can vary from a dark green to almost a reddish color.
The reason you're not getting the result you're looking for is: water is transparent. You have a very dark default ground, that's also infinitely deep. Try placing a bright, sand colored surface at a realistic distance below the water surface and it will look much more like what you expect!
