Blue is my absolute favorite color of all time.

Mine too! It's one of three primary pigment colors in painting or the RGB color model. Makes sense that lots of people enjoy it!

I love that the sky is blue too.

And the ocean! It's weird, but most blues actually contain mixtures of other colors, like green in azure, or violet in ultramarine.

There is nothing more beautiful than blue ocean water. Is there a natural mineral that can make the color blue?

The deep sea actually appears blue because of an optical effect known as Rayleigh scattering. Same thing as the clear daytime sky!

That's very interesting. I always wanted blue eyes, too. But I have brown instead.

Well, the appearance of blue in eyes results from the Tyndall scattering of light in a stroma. It's actually incredibly similar to Rayleigh scattering, which makes the sea blue!
