# Milk-White Sky

The Milk-White Sky is the uniformly bright, pale sky common in PWCN standard climate-controlled zones, produced when stratospheric aerosols reflect and filter direct solar radiation.

## One-Sentence Definition

The Milk-White Sky is the uniformly bright, pale sky common in PWCN standard climate-controlled zones, produced when stratospheric aerosols reflect and filter direct solar radiation.

## Formation Mechanism and Social Significance

To reduce cooling costs and stabilize energy flux, the system weakens direct sunlight, producing a diffuse, low-shadow, nearly featureless white sky. It is the sky most familiar to the majority of residents and simultaneously symbolizes safety, energy efficiency, and sensory monotony.

## Limitations and Information Boundary

The Milk-White Sky is not a natural cloud layer, nor does it mean that every PWCN-controlled zone must display the same landscape. Premium subscription zones can schedule different lighting and weather effects.
