I love blue, Blue is one of the three primary colours of pigments 
I see, it reminds me of the blue sky. What about you?
Same, It lies between violet and green on the spectrum.
I was not aware of that. I think thats why its such a cool and calm color.
I have read that dominant wavelength between approximately 450 and 495 nanometres
Thats quite a small wavelength compared to other colors 
it is! Most blues contain a slight mixture of other colors like azure and teal
