A subtrope of Mood Lighting common in Science Fiction and Forensics shows. Shots are suffused with vaguely blue lighting. This is usually complemented by stark, overly bright desk lamps. Occasionally this infects outdoor scenes, making sunny days look more overcast; this should not be confused with the dark blue camera filter used in shooting "day for night". Although this is a good way to cover up a lower-budget set, the light can sometimes become glaring and/or induce too many shadows. Nowadays, the rise of Orange-Blue Contrast makes this nearly ubiquitous in mainstream movies and television.
