No volcanic eruption in human history has darkened the entire world. But about 535 AD a volcano at Krakatoa erupted so violently it may have darkened the sky around the world to an extent that it caused famines and threw Europe into the Dark Ages (they are not called the Dark Ages because the sky was dark, rather it was considered to be a period of intellectual darkness).
A volcanic eruption here on Earth can not affect the Sun. However, a volcanic eruption here on Earth can put particles of ash and some volcanic gases into the atmosphere that affects the transparency of Earth's atmosphere to sunlight. With the ash content the skies near the volcano go dark during the day and with the gases (especially sulfur oxides) the amount of cloud cover increases causing sunlight to be reflected and the air to cool.
Pliny the Elder wrote a detailed account of the eruption of Mount Vesuvius in 79 AD, describing the dark cloud, ash fall, and devastation caused by the eruption. He also mentioned his nephew, Pliny the Younger, who witnessed the event and described it in his own letters.
A grey eruption is when the pressure builds with magma, when it fills up, rock and gas are blasted km in the air, Red on the other hand is very slow, but its lava is red hot Hope this helps !
andesite
Scoria is typically found in volcanic environments, such as volcanic craters or areas where volcanic eruptions have occurred. It forms when lava cools rapidly and traps gases inside, creating a porous structure with a dark, reddish-brown color.

Obsidian
November 8 1898 eruptionReports of eruptions in the Ruby Mountain area about 80 km south of Gladys Lake, near the end of the 19th century. Miners working in the area were able to work during the dark nights, due to the glow of the eruption. There have been no evidence of the eruption found in the region, however, the volcanic activity in the region is young enough to have been the site of an historical eruption, although the 19th century report of the eruption is not yet known.
it caused civil wars to break out

Basalt is the most common volcanic rock. It is a dark-colored, fine-grained volcanic rock that is found in many volcanic settings around the world. Basalt forms from the rapid cooling of magma on the Earth's surface.
