Who Colored the Berg?

White light is made up of all the colors of the rainbow (red, blue, violet, etc.) and each color has a different wavelength.

Icebergs are white because the ice is full of tiny air bubbles. The bubble surfaces scatter all color wavelengths by the same amount, giving the iceberg an overall white appearance. (Water and ice in clouds scatter color wavelengths the same way, and they also appear white.)

The blueish streaks of clear, bubble free ice often seen in icebergs results from the refreezing of meltwater which fills crevasses formed in the glacier as it creeps over land.

Ice that is bubble free has a blue tint which is due to the same light phenomenon that tints the sky - the wavelength of blue light causes it to be scattered or spread around much more than the other colors, and this scattered blue light is what makes the sky (and bubble free ice) blue.
