Expert Answer
Bluish Oceans
The sunlight or scientifically, the white light from the sun actually consists of seven colors i.e.
violet, indigo, blue, green, yellow, orange and red in the increasing order of the wavelength.
The ocean looks blue because red, orange and yellow (long wavelength light) are absorbed
more strongly by water than the blue color (short wavelength light).
So when the white light from the sun enters the ocean, it is mostly the blue that gets returned (reflected).
Therefore, the oceans appear bluish due to the reflection of blue color.

White Clouds
Scattering of light takes place at a very large scale in the clouds of the atmosphere.
Scattering is a process in which light in the form of propagating energy is scattered due to various obstructions.
The vapour droplets in clouds acts like an obstruction and scatters the light rays of all the wavelengths at a uniform rate.
Therefore, the clouds appear to be colorless or white in color..
