This happens due to the Rayleigh scattering effect. The light is scattered among the air molecules and the shorter wavelength (blue) disperses out the furthest, so we see a blueish tint.

There are many rock types in the Blue Ridge Mountains include quartz and granite.
The Blue Ridge Mountains, or Smokies, are located in North America. They span several states, including Tennessee and Kentucky.
The Blue Mountains are colder due to their higher elevation, which results in lower temperatures as you go higher up. Additionally, the Blue Mountains are located in a region that experiences cooler weather patterns compared to lower altitudes.

Some clams appear to have blue lips but in reality, they don't. The lips appear to be blue due to the reflection of their lips in the water.

Mountains can appear purple in the distance due to atmospheric scattering of light. When sunlight passes through the atmosphere, shorter wavelengths like blue and green are scattered, while longer wavelengths like red and purple are allowed to pass through. This causes distant mountains to appear blue or purple as the shorter wavelengths are filtered out by the atmosphere.
Mountains can appear blue in the distance due to an optical effect called "atmospheric perspective." This occurs because as light travels through the Earth's atmosphere, shorter wavelengths of light (such as blue) are scattered more than longer wavelengths, giving distant mountains a blue hue. Additionally, the presence of water vapor, dust, and pollution in the air can further enhance this blue appearance.

The blue mist flowers appear in the mountains every other day in the fall.
Asheville, NC is in the Blue Ridge Mountains. That's 374 miles from Albany.
Distant things appear bluish because of the atmosphere. This is particularly noticeable with things that are large enough for you to actually see from miles away, like hills or mountains. Since "Blue Hills/Mountains" is a pretty common term, I don't know which specific ones you're referring to. It's also possible they're called that because the stone they're made of is bluish in color.
usually just snow or glaciers give a reflecting effect which causes mountains to appear white or even blue sometimes from a distance

If you are drawing or painting a landscape, the mountains are generally colored with a bit more gray perhaps with a bit of blue or purple mixed in. If you have been in the mountains, distant mountains look a bit grayer and less detailed the further away they are.
