Water is a tasteless, odourless liquid at ambient temperature and pressure, and appears colourless in small quantities, although it has its own intrinsic very light blue hue.

Water is clear, BUT, the colour it seems to be depends on the conditions that it is viewed in, for example, clear sea water seems blue because it filters out the blue light rays from the sun's light, the same as the sky does.

Water is Blue. If you look into a swimming pool you'll notice the blue tinge. icebergs also exhibit this in white and blue stripes. The white is all the gas bubbles compressed from the water the Blue is the water itself.
The colourless bit is a common misconception. As is the misconception the blue is a reflection of the sky.

It isn't any colour, it's clear! Sea water has a green or blue colour but this is the reflection of the sky. It can also be murky, but that's only because of all the seaweed, creatures and matter that are in it. Water, in its purity, is clear.

An object has to be opaque or translucent to be able to be classified as being "coloured". An object absorbs, reflects, and transmits certain fractions of light incident on it, and depeding on these fractions, it's classified under the categories I mentioned above. Opaque objects do not transmit any light. Translucent objects transmit light, but absorb certain frequencies more than others, hence the transmitted light contains more of a certain colour, like green, for example. Pure water is transparent, and to the naked eye, it'll transmit all colours of the light equally and almost totally (almost none will be reflected or absorbed), hence it will appear colourless.

It is blue. You just need a lot of it to detect the colour.
Note: I've provided sources from reputable locations (I'll admit that one of them is wikipedia, but some folks belive it to be reputable, so it's there as well).
My second source link is an article from the Journal of Chemical Education, complete with spectrophotometer analysis and so forth.
The link to the pic of super-pure water from the madsci site isn't working, so I've found another photo and provided it just below.

Water's colourless. The sea's blue cos it reflects the sky - the sky's blue because it's about 80% nitrogen, which is v faintly blue - you can see it's blueness in the sky and not in the air around you because you're looking up at so much of it in the sky. Water can be other colours because of what's in it - algae can make it green, mud makes it brown etc. lol xx

pure water is colourless. the colours and hues that we see when looking at the sea or rivers is a combination of the reflection of the sky and impurities and suspended particles within the water

water has no colour, unless it has chlorine added which we have in Australia and then it may appear a whitish colour
and if you live in some areas it may be brown due to low water levels in the dam

hi,
Water is clear it is light reflecting off the different impurities that make it appear different colours.
That is why a lake or river from a distance can appear blue and the sea appears to be greeny blue.
