What is your favorite color? Mine is blue. 
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?
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? 
Glad you like it! Yes, woad is an old vegetable dye. I think they tried to replicate it in the movie Braveheart. Must check out Sweden's flag.
Well, I have learned a lot from you today! I'll check out woad. I wonder if it is related to indigo.
I guess so. Indigo is what replaced it as indigo is apparently finer. My friend is learning about vegetable dyes - I'll ask.
