Because sky is in blue colour. So the sea looks light blue in colour.

Because blue light has a higher frequency and is more penetrating that other colors. When light hits the water, it reflects from all different depths. Lower frequency light has a greater tendency to scatter before it can be reflected back out of the water and reach your eyes, so the reds, yellows and oranges are filtered out. This is why the sea usually appears bluish green.

Isn't.
The Med, for example, is often brownish. This comes from the fact that it is a shallow sea; so that the bottom sediment often mixes with the water.
The oceans around the Antarctica are often very deep blue...almost black. This stems from their depth and from their purity...very few people to pollute the water down there.
The blueish colors, deep and light, stem from the fact that water filters out the longer light waves, like red, orange, yellow, and green, and lets the shorter ones, like blue, indigo, and violet, through. Thus, as light penetrates deeper into the water, more and more redish light is filtered out, which is why the deeper water is bluer (more red is filtered out).

its not - its a reflection of the sky - i guess the sky is always light blue for you - if you stayed somewhere cold and grey the sea would be grey

sea is not always blue in color.
at the time of sunrise&sunset it will be somewhat reddish.This is due to the scattering of light.At sunset & sunrise,the sun is so far to the horizon,so waves with low wavelengths scatters &vainishes.At all other time,the rays with low wavelength like violet&indigo,scatters alot and spreads over sky and sea

It's not.
It's only light blue in shallow waters, with light sandy seabeds, and in sunny weather.
Other times it can vary from that colour, through darker blues, to dirty grey.
