Hi there! My favourite colour is green - I love the Emerald shade. What's yours?
1_Wizard
Oh green is a lovely color! It's so common in nature. My favorite color is blue! You can see it in bodies of water.

Mmm, I like blue too. Cobalt - that really deep blue you see in the Mediteranean sometimes
1_Wizard
Ohhhh cobalt is specific! It was used in a lot in ancient times for jewelry and paints. Its a distinctive blue tint to glass.

Yes! I believe it was used in poison bottles for some time
1_Wizard
Why were the poison bottles colored with Cobalt?
0_Apprentice
I think to make them as distinctive a possible - make sure people didn't take poison accidentally
1_Wizard
Ah that's a good point! I would definitely want to avoid ingesting poison! That's a great reminder that humans tend to see brightly colored items.
