I love the color blue and it is one of the three primary colors in painting.
I like blue as well. Unfortunately it is cloudy here and the sky is gray, not blue.
It is sunny here finally and the clear day sky and the sea appear blue because of an effect called Rayleigh scattering.
What exactly is the Rayleigh scattering?
Rayleigh Scattering is the elastic scattering of light or other electromagnetic radiation by tiny particles.
Interesting. Sort of like a rainbow.
Rainbow
A rainbow is a meteorological phenomenon that is caused by reflection, refraction and dispersion of light in water droplets resulting in a spectrum of light appearing in the sky. It takes the form of a multicoloured circular arc. Rainbows caused by sunlight always appear in the section of sky directly opposite the sun.
Rainbows can be full circles. However, the observer normally sees only an arc formed by illuminated droplets above the ground, and centered on a line from the sun to the observer's eye.

Blue
Blue is one of the three primary colours of pigments in painting and traditional colour theory, as well as in the RGB colour model. It lies between violet and green on the spectrum of visible light. The eye perceives blue when observing light with a dominant wavelength between approximately 450 and 495 nanometres. Most blues contain a slight mixture of other colours; azure contains some green, while ultramarine contains some violet. The clear daytime sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering.
