Blue is one of my favorite colors
That is interesting - most blues actually contain a slight mixture of other colors, like green or violet.
I didn't think green would be in the mix!  Although, I know blue is in green, of course.
It has been an important color in a lot of decorations and art since ancient times, so it's been used creatively for a long time.

Many years ago the Chinese even used cobalt blue for blue and white porcelain.
That's true.  I think in France there is a cathedral with stained glass that is a shade of blue that no one can figure out how they created.
I think European artists used it in the Cathedral windos.
I ahve seen that kind of porcelain.  I'm sure it's worth money.
Chinese ceramics
Chinese ceramics show a continuous development since pre-dynastic times and are one of the most significant forms of Chinese art and ceramics globally. The first pottery was made during the Palaeolithic era. Chinese ceramics range from construction materials such as bricks and tiles, to hand-built pottery vessels fired in bonfires or kilns, to the sophisticated Chinese porcelain wares made for the imperial court and for export. Porcelain was a Chinese invention and is so identified with China that it is still called "china" in everyday English
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.
