I love the color blue.
Its a great color. It is one of the three primary colors.
What are the other two?
I believe Green and Red. Blue lies between green and violet on the visible light spectrum.
Yes.  I like blue better than purple or red  - maybe because the sky is such a pretty blue
Same here. There is an optical effect called Rayleigh scattering that causes the blue color of the sky and ocean.
That is interesting to know.   It is interesting how our eyes see color and how some people are color blind
I am glad I am not color blind. Blue was also widely used in decoration and art since the ancient times.
