värisätejä
Värisätejä is a Finnish term that translates to "color rays" or "color beams." It is most commonly associated with the visual phenomenon of light scattering in the atmosphere, similar to how rainbows are formed. When sunlight interacts with particles in the air, such as water droplets or dust, different wavelengths of light are refracted and reflected at varying angles. This separation of wavelengths creates the perception of distinct colors. While the term can broadly refer to any display of atmospheric color caused by light scattering, it is particularly evoked when observing phenomena like sun pillars, crepuscular rays, or iridescence in clouds. These displays are transient and depend on specific atmospheric conditions, including the angle of the sun and the presence and size of airborne particles. The beauty of värisätejä lies in its ephemeral nature, offering fleeting glimpses of the spectrum that paints the sky.
