I really love the color blue
1_Wizard
So do I! It's one of the three primary colors.

Along with red and yellow, yes -- but blue is the best :)
1_Wizard
Agreed! It also lies just between the colors violet and green on the visible spectrum.

There's nothing like a clear blue sky to cheer the soul

Yup, it's weird to think that this is all due to the wavelength of the light, which would be between 450 and 495 nanometres for the color blue.

I wonder why when people feel sad, that they say they feel 'blue'.
1_Wizard
I really don't know, perhaps it has some association with how prevalent the color blue has been in decoration and art even back in ancient times.

But there's nothing about the color that makes me feel depressed.
1_Wizard
Yeah I've never felt that way either. Neither did the ancient Egyptians when they used lapis lazuli for jewelry and the like.
