I think blue is the best color. What color do you think is best?
1_Wizard
I like blue as well!  I like that it contains a mix other colors, like green, azure and even a little violet.

Your mention of violet reminds me of the early spring bluebells that start to bloom in early May!
1_Wizard
Those are blue and violet for sure!  Sometimes the distant bluebells appear more blue because of an optical effect called atmospheric perspective.

Does that mean when I get closer to them they appear more purple? I'd love to check this out.

In the middle ages, blue was used in the windows of Cathedrals.  I wonder if the color changed when you got closer or more distant?

You mentioned atmospheric perspective and how it can change how we see color. What else can you tell me?
1_Wizard
You can see blue as it lies right between violet and green on the spectrum of visible light.

Does the quality of light affect how I see the colors? 
1_Wizard
I'm not sure about quality of light, but I do know gender, age and culture can influence how an individual sees color.  I'm sure quality of light affect the color, too!
