The Relationship Between Hue of Light Pollution and the Visibility of Celestial Bodies

This study investigates the impact of different hues of artificial lighting on the visibility of celestial bodies. Light pollution has been recognized for its adverse effects on ecological systems, human health, and astronomical observations. This research examines how various LED colors—white, blue, green, red, yellow, and magenta—affect the visibility of stars. Using a LED lantern with colored filters, the study simulated ambient light pollution and measured its effects on the visibility of selected stars. Data analysis revealed that warmer colors (e.g., red and yellow) tend to result in less light pollution and better visibility compared to cooler colors (e.g., blue and magenta). The study suggests that implementing warmer-toned LEDs could mitigate light pollution. <br>
