Animals typically use the color green as camouflage, blending in with the chlorophyll green of the surrounding environment. Green animals include, especially, amphibians, reptiles, and some fish, birds and insects. Most fish, reptiles, amphibians, and birds appear green because of a reflection of blue light coming through an over-layer of yellow pigment. Perception of color can also be affected by the surrounding environment. For example, broadleaf forests typically have a yellow-green light about them as the trees filter the light. Turacoverdin is one chemical which can cause a green hue in birds, especially. Invertebrates such as insects or mollusks often display green colors because of porphyrin pigments, sometimes caused by diet. This can causes their feces to look green as well. Other chemicals which generally contribute to greenness among organisms are flavins (lychochromes) and hemanovadin. Humans have imitated this by wearing green clothing as a camouflage in military and other fields. Substances that may impart a greenish hue to one's skin include biliverdin, the green pigment in bile, and ceruloplasmin, a protein that carries copper ions in chelation.

During the Hundred Years' War, the army of the Duke of Burgundy and a force of about two hundred English soldiers occupied Paris from May 1420 until 1436. They repelled an attempt by Joan of Arc to liberate the city in 1429. A century later, during the French Wars of Religion, Paris was a stronghold of the Catholic League. On 24 August 1572, Paris was the site of the St. Bartholomew's Day massacre, when thousands of French Protestants were killed. The last of these wars, the eighth one, ended in 1594, after Henri IV had converted to Catholicism and was finally able to enter Paris as he supposedly declared Paris vaut bien une messe ("Paris is well worth a Mass"). The city had been neglected for decades; by the time of his assassination in 1610, Henry IV had rebuilt the Pont Neuf, the first Paris bridge with sidewalks and not lined with buildings, linked with a new wing the Louvre to the Tuileries Palace, and created the first Paris residential square, the Place Royale, now Place des Vosges.
What was the date of the St. Bartholomew's Day massacre?
A:
24 August 1572
