it’s often difficult to judge how certain tile colors will look in a swimming pool filled with water. Searching through many different tones of blues and greens from numerous samples and swatches can make the decision even more confusing especially when you also need to consider how colors can change when in water. And on top of that, it’s important to remember that the color of your pool can be affected by a number of different outdoor elements such as the color of the sky at any given time, shadowing from trees and buildings and the depth of the pool. The surrounding colors in terms of coping, paving and house can also influence the tone of color in the pool.
