Quick Answers
Sea blue is a deep shade of blue that resembles the hue of the open ocean. It is lighter and brighter than navy blue but darker and deeper than sky blue. The exact shade of sea blue can vary depending on factors like the depth of the water, time of day, and weather conditions. Some common shades described as sea blue include aqua, azure, teal, cyan, and cerulean. Sea blue can range from greenish-blue hues to blue-green hues.
The Science of Sea Blue
The bluish-green color of the sea is a result of how water absorbs light. When sunlight hits the ocean, some colors on the light spectrum are absorbed more than others. The blue and green wavelengths of light are able to travel deeper into the water, while the red end of the spectrum is quickly absorbed at shallow depths.
This selective absorption process makes the water appear blue and green to our eyes. The exact shade depends on factors like:
| Factor | Effect on Sea Blue Shade |
|---|---|
| Water Depth | Shallow water reflects more sky blue; deeper water appears darker blue |
| Water Clarity | Clear water is deeper blue; sediment makes water appear greener |
| Viewing Angle | Straight-on angle reflects sky blue; side angle captures more green |
| Time of Day | Overhead sun casts blue; low sun brings out green tones |
| Weather | Cloudy skies create dull, flat blue; bright sun enhances vibrant blues |
As light passes through successive layers of water, more red wavelengths are absorbed, causing the remaining light to take on a deeper blue-green hue. The maximum depth of sunlight penetration depends on water clarity and averages around 200 meters in the open ocean.
