Put these three things together, and a blue sky is inevitable. Here's how it all comes together. Light of many different wavelengths, not all of which are visible, are emitted by the Sun.

In actual fact, the sea is blue for similar reasons as the sky. When sunlight hits the ocean, the colours with longer wavelengths, red, orange, yellow and green, ar absorbed so that blue is left over.

That’s what we see when we look up at a blue sky. The light – especially the blue light – is splattered and scattered so much that wherever we look, we see a blue glow.
