Pure water is visibly blue due to absorption of light in the region c. 600–800 nm. [88] The color can be easily observed in a glass of tap-water placed against a pure white background, in daylight.

The sea is seen as blue for largely the same reason: the water absorbs the longer wavelengths of red and reflects and scatters the blue, which comes to the eye of the viewer. The deeper the observer goes, the darker the blue becomes. In the open sea, only about 1% of light penetrates to a depth of 200 metres (see underwater and euphotic depth).
The web color light blue is part of the X11 color system, with a hue code of 194. This color is closer to cyan than to blue. Variations of this color are known as sky blue, baby blue, or angel blue. The first recorded use of "light blue" as a color term in English is in the year 1915.
