Hello. What is your favorite color? I like blue. It's one of the three primary colors in painting.
I personally like green but I think it varies based on my mood.

what does that mean? 
It can influence perceptions that are unconscious, such as how food tastes. It also can enhance the effectiveness of placebos. 
Ah, that is interesting. Is it because some colors are associated with certain emotions - such as blue and sadness
Most blues have a mixture of other colors , azure has some green, and aquamarine has violet. It is hard to tell.
Do you like to paint?

Blue
Blue is one of the three primary colours of pigments in painting and traditional colour theory, as well as in the RGB colour model. It lies between violet and green on the spectrum of visible light. The eye perceives blue when observing light with a dominant wavelength between approximately 450 and 495 nanometres. Most blues contain a slight mixture of other colours; azure contains some green, while ultramarine contains some violet. The clear daytime sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering.
