A cyanometer is a scientific instrument designed to measure the intensity of the sky’s blue color. It uses a scale of numbered blue shades that observers compare directly with the sky. The reading reflects how molecules, dust, and water vapor in the atmosphere scatter sunlight. Darker blues usually appear at higher altitudes where the air is thinner and cleaner, while paler skies suggest more particles or humidity affecting how light is diffused. You can easily make a simple cyanometer at home using paper, blue shades, numbering, and comparing it with the sky. Want more interesting content like this ?
