15 'Facts' You're All Wrong About

13. Water Is Colourless, Clear And Transparent

€œIt is, though. Everyone knows that €“ the sea is only blue because it reflects the colour of the sky. That€™s why the sea looks grey and darker under a cloud. You can argue all you like, but that€™s science. I€™ve scienced you.€
Science this: water is intrinsically blue. A very, very light shade of blue €“ but the more of it there is, the bluer it appears. It€™s down to a weak absorption of the red component of light: very small volumes of water (like the half-full, half empty glass you use to see if you€™re in a good mood or not) appear colourless, while larger volumes (like swimming pools) take on the correct blue tinge as light travels further through it. It€™s true that, outdoors, the reflection of the sky will play a part. It€™s also true that impurities in water (of which there are often many) can filter light in various ways to achieve other colours, like green: but the water would still be intrinsically blue even if the sky was mauve with yellow polka-dots and even if the water was clogged with chocolate. That€™s what intrinsic means.
