Over Sweet? --- Day 10/170

Walk: No, big Necessary rainstorm

Distance: 0, yoga

Berthe Morisot (French, 1841-1895), Blanche (Fillette aux jacinthes), ca. 1875,
Pastel over charchol on paper, laid down on canvas

There is something about the straight forward, cool colored clarity of this portrait that appealed to Ciwt in the Legion's current Pastel Show.*

Maybe others find it (overly) sweet and a candidate for Ciwt's Halloween Contest.**

Each to his or her own in art.

*Color Into Line: Pastels from the Renaissance to the Present, Legion of Honor, October 9 - February 13, 2022

Here is a picture of the artist, Berthe Morisot @1860. Ambitious, focused, privately trained/relentlessly innovative and one of only two women welcomed into the company of Paris's Impressionist painters. Ciwt doubts Morisot was overly sweet.

Feeling A Little Green --- Days 10/166 & 167

Walk: 1. LP Nails 2. No

Distance: 1. 1.5 miles, then much energy spent contacting Delta to cancel trip 2. 0, enjoying a bit of rain

So the Legion of Honor's Pastel Show opened a little while ago. It is not a medium that particularly stimulates Ciwt, but she was curious to learn why green was such a difficult color for pastel makers to develop.

You see a lot of portraits done in pastel since the time of Leonardo (1452-1519) but not any landscapes until the 1800's. It was then that sticks of pastel in the color of trees, grass, shrubs, pond scum - basically the color chlorophyll brings to nature - were finally available. One has to wonder though about the health of the artists who worked often with those greens because many hues of it were and are still toxic. Besides being a notoriously difficult color to come by, green pigments have been some of the most poisonous in history.

If the color is fabricated solely from natural substances such as plants, it will fade quickly. Since ancient times the solution to green's color longevity has been to mix it with some other chemical substance. Ancient Egyptians tried using copper malachite to paint tomb walls, but it was expensive and easily turned black. Later the ancient Romans soaked copper plates in wine to create verdigris which is a faded hue you see on old coins, frescos, medieval manuscripts but doesn't truly imitate the greens of nature.

One of the first to invent a bright, lasting green hue was a Swedish chemist named Carl Wilhelm Scheele. In 1775 he accomplished that by using the toxic chemical arsenite. Unfortunately. Called Scheele's Green, it was so popular that it had replaced earlier mineral and vegetable dyes by the end of the 18th century. It was used on paper, wall hangings, fabrics, children's toys. Again, unfortunately! Journals of the time contain reports of children turning ill in bright green rooms and ladies in green dresses becoming sick from consuming toxic vapors. Some historians believe the pigment caused the death of Napoleon whose bedroom wallpaper featured the deadly hue.

Toward the mid-1800's Scheele's green was replaced by Paris Green. Another unfortunate development because it was still highly toxic and very popular with artists. It was the pigment used by French Impressionists such as Claude Monet, Paul Cezanne and Pierre-Auguste Renoir to create their lush green landscapes. Paris Green may have been responsible for Cezanne's diabetes and Monet's near blindness. In the 1960's it was finally banned.

Today, green is associated with being environmentally conscious—“being green." However, despite all the modern advances in color technology, producing green dyes and pigments is still difficult and many hues continue to feature toxic substances. One of the most common shades today is called Pigment Green 7. Used in plastics and paper, it contains chlorine, which, when consumed, is known to lead to illness and even death. Another popular hue is Pigment Green 36, which also includes chlorine as well as potentially hazardous bromide atoms. Also on the list, the popular bright Pigment Green 50 is a toxic cocktail of cobalt, titanium, nickel, and zinc oxide.

Oh dear, as Ciwt looks around her green painted rooms, she's beginning to feel a bit queazy.
