A planet where the same side is always facing the primary star may never have sunset, because the sun is always either facing that part or on the other side of the planet (either always night or always day).
Additionally a planet with more than one sun may, by some freak of nature and physics, have permanent daylight over some, most or all of its surface while any unlit area remains unlit forever. For the same reason as above, always night or always day, so no sunset.
Sunset times occur later in summer and earlier in winter due to the tilt of the Earth's axis. In summer, the Northern Hemisphere is tilted towards the sun, leading to longer days and later sunsets. In winter, the Northern Hemisphere is tilted away from the sun, resulting in shorter days and earlier sunsets.
The eruption of Mt. St. Helens in 1980 released a huge amount of ash and dust into the atmosphere, affecting weather patterns globally. The ash cloud caused cooling temperatures in the region, disrupted air travel, and resulted in colorful sunsets known as "volcanic sunsets" around the world.
Olive green is a color that is similar to an earthy green tone. It has a mixture of green and brown undertones, giving it a natural and earthy feel.
The sky is blue because the atmosphere scatters sunlight. Light with shorter wavelengths (blue, purple, violet) is scattered more in the atmosphere, so the sky appears blue; this is the same reason that sunsets and sunrises appear red and orange: at sunset/sunrise, the sun's light hits the atmosphere at a low angle, increasing the distance that the light must travel through the atmosphere. Thus, more colors are 'scattered out', even the blue-end of the spectrum, leaving red and orange colors.
Scott Bachmeier, a research meteorologist at the Cooperative Institute for Meteorological Satellite Studies at UW-Madison, says that particles in the air scatter light. In the day, the particles scatter more violet and blue light, but our eyes are more sensitive to blue light - that's why the sky appears blue. Thunderstorms, which can be the home of tornadoes, usually happen later in the day, when the sun is approaching the horizon. That creates a reddish tinge in the sky, as any fan of sunsets knows. But light under a 12-mile high thundercloud is primarily blue, due to scattering by water droplets within the cloud. When blue objects are illuminated with red light, Bachmeier says, they appear green. Green is significant, but not proof that a tornado is on the way. A green cloud "will only occur if the cloud is very deep, which generally only occurs in thunderstorm clouds," Bachmeier says. "Those are the kind of storms that may produce hail and tornadoes." Green does indicate that the cloud is extremely tall, and since thunderclouds are the tallest clouds, green is a warning sign that large hail or a tornado may be present. If this explanation is confusing, Bachmeier offers some alternative folk wisdom for the color change: that tornadoes sucked frogs and grasshoppers into the sky.

Sunsets and sunrises have different colors because of the way sunlight interacts with the Earth's atmosphere. During sunrise and sunset, sunlight has to pass through more of the Earth's atmosphere, which scatters shorter wavelengths like blue and green light, leaving longer wavelengths like red and orange to dominate the sky. This scattering effect is what gives sunsets and sunrises their vibrant colors.
