What is your favorite color? Mine is blue. 
1_Wizard
Mine is green, but I like blue too and blue is apparently between violet and green.

Ah, yes, that's true, they are close to each other on the color wheel. Blue is my favorite because I find it very calming.

You would like the Scottish flag then (where I'm originally from) - it's blue and white

Ah, I will have to look it up!  I'm sure it is beautiful. What shade of blue is it?  Navy blue?
1_Wizard
It's more of a navy blue, the white part of the flag is in the shape of an X, with the blue in the background. Europeans used to dye their clothes blue with woad centuries ago.

I've just looked it up, it is lovely. I also like the flag of Sweden.  I didn't know that about dying clothes blue with ...woad?
