My favorite color is blue. How about you?
Same here! What shade of blue do you like most?
I generally lean towards the darker shades. More azure. Blue is one of the three primary colors in the RGB model
I do as well, but I do really like sky blue. And cool, aren't the others red and green?
Yes they are! And, blue lies between violet and green in the visible light spectrum
That makes sense, what wavelength is blue light then?
The wavelength of blue is approximatly 450 to 495 nanometers
Interesting! You really know a lot about blue!
I do! Also, the sky and sea appear blue due to the optical effect of Rayleigh scattering
I've heard of that, but I never really knew what it was before.
