Blue is my favorite color...

But which blue is the sky?
Did my photo even capture the right color? when I heard that Alexander von Humboldt had a cyanometer to measure the blueness of the sky, I decided that I need one, too.

What is "sky blue"? I've taken painting classes and am not sure I've ever achieved sky blue. I remember that Dr. Raabe was looking for a sky-blue flower. I wonder if he ever found it. And measuring its wavelength seems like cheating.
