• Green: The most common and often visible color to the naked eye is green. It's caused by the collision of charged particles from the sun with the Earth's atmosphere. These particles, mostly electrons, excite oxygen atoms in the atmosphere, causing them to emit green light.

• Red: Occasionally, when the aurora is very active, red may be visible to the naked eye. Red auroras are typically seen at lower altitudes and are caused by high-altitude oxygen molecules being struck by solar particles.

• Purple and Pink: These colors are less common but can sometimes be observed. They result from a mix of various atmospheric gases and solar particles, and they tend to appear near the edges or lower portions of the auroral display.

Cameras, with long-exposure settings, can capture more colors and details in the Northern Lights that might not be as visible to the naked eye due to their ability to collect and record faint light over time. Here's how cameras can capture the Northern Lights:

• Reds and Purples: Cameras vividly capture reds and purples, notably during intense auroral displays. They excel at detecting subtle light variations, often less noticeable to the human eye.
• Vivid Colors: Cameras may capture colors like magenta, violet, and deep red, creating stunning and vibrant aurora photos. Structure: Cameras can reveal intricate structures and patterns in the aurora that might be less apparent to the naked eye.
• Extended Range: Cameras can also capture a broader range of colors and auroral features by taking long-exposure shots, which accumulate light over time, revealing more details and color variations.
