grey clouds
The sky typically appears gray or white just before it snows due to thick cloud cover blocking out sunlight.
Any kind of light-colored, aluminum blinds will do a good job of blocking sunlight.
If it's an ash volcano then the ash forms into a cloud and can be the size of a country such as Ireland, and the cloud can travel the world due to the wind, blocking out sunlight above the country it is currently above.
Blocking sunlight helps to cool the Earth by reducing the amount of solar radiation that reaches the Earth's surface. This can be achieved through methods such as cloud seeding, aerosol injections, or deploying reflective materials in space. By reducing the amount of sunlight that reaches the Earth, less heat is absorbed, leading to a decrease in global temperatures.
A region underneath cloud cover will likely have cooler temperatures due to the blocking of sunlight heating the surface. It will also have increased humidity levels and potentially higher chances of precipitation compared to a region with no cloud cover, which tends to have warmer temperatures and lower humidity levels.

No, a translucent material is not the best choice for blocking out sunlight from windows, as it allows some light to pass through. For effectively blocking sunlight, opaque materials are preferable, as they completely obstruct light. Translucent options may provide some diffusion and reduce glare, but they won't offer full darkness or UV protection. For optimal sunlight blocking, consider using blackout curtains or shades.
It seems like PVC is the best umbrella fabric for blocking sunlight. It blocks 100% of the suns harmful UV rays and it can withstand harsh weather. Another good option is canvas which is effective for blocking sun but is not good for blocking out rain.
It's described as cold usually or that there will be bad weather.
A dark line in the sky visible from the ground could be caused by a phenomenon like a solar eclipse, a passing storm cloud, or pollution in the atmosphere blocking sunlight.
