![]() ![]() Red, for example, is the least-intense color on the spectrum and is filtered out at rather shallow depths. This process of absorption has the greatest effect on the colors we think we see underwater,(that is, the perceived color). Some colors are not as intense and are absorbed rather quickly, while others are able to penetrate deep into the water. (Scuba divers know these optical tricks but all the same, principles apply.) As a byproduct of this process, various colors of the light spectrum are absorbed by the water at different rates. The hole with the water in it will be darker at the bottom. This is why, in two holes of equal depth, one empty and the other filled with water. Īnd that’s not all: Light is also absorbed as it passes through water and dissipates rather quickly. And because the light is scattered as it passes through water, the deeper you go, the less contrast objects will have, which is why objects lying on the bottom of a 20-foot-deep pool seem washed out visually. This happens because light travels more slowly in water than it does in the air as a result, not only do objects appear bent, they also appear larger than they really are. If you doubt this, take a long stick and poke a length of it beneath the surface: It will appear to bend just below the waterline. This is why, when you stand on the side of a pool and look at underwater objects, those objects aren’t quite where they appear to be. When placed in a pool or fountain, it does not assume the color of its surroundings, as though it were a chameleon instead, because of the applicable physics, water has some interesting interactions with light, bending it in a phenomenon which is known as refraction. Topping the list of these factors is the way optical physics inevitably works in water.īasically, water is clear rather than tinted (at least, if the water is clean). This is why working with the client’s request for a blue interior finish is no guarantee that the pool will appear blue once the vessel is filled with water. ![]() While there is some relationship between the interior surface color and the appearance of the water, a range of factors affects the perceived color of the water in a swimming pool, fountain or spa. What most people don’t understand is that a myriad of variables and principles are involved in determining what color water appears to be. Most clients come in and say “I want the pool finish to be blue so that the water will look blue”. Using Color Theory to choose what color finish would be best for your pool, spa, and or fountain.Įven though most people think it’s simple, working with color in the presence of water is surprisingly complex. ![]() Please note that the water color may differentiate based on lighting, angle, water depth, and the surrounding landscape.
