Night Vision

Night Vision is a status effect that enhances the player's ability to see in darkness and underwater.

Effect

Night vision greatly increases the brightness, so the player can easily see in a light level of 0. However, it is not as bright as a light level of 15 (e.g. with the "Moody" brightness setting, it is similar to block light level 12–13 and no sky light in the Overworld within the "Bright" brightness setting), and unlike block lighting it is not tinted. As such, the player can distinguish between light levels. With Vibrant Visuals, the game specifically enhances the gamma of ambient light (noticable without other light sources) and sky light during nighttime. If the player has Night Vision without Vibrant Visuals, the fog's color in gets brightened depending on the biome. It turns bright red in nether wastes and crimson forest, magenta in warped forest, bright cyan in soul sand valley, gray-white in basalt deltas, and pale purple in the End. In Java Edition 20w14∞, in certain dimensions with unique lighting, the player can see the color spectrum that is not parts of the vanilla lighting system (e.g. vivid shades of green, blue, etc.) easily as the effect is not as fully bright, even with the "Bright" brightness setting (in other cases, in some dimensions (such as Easter Egg dimensions like ant) already have the full brightness at any light levels (including light level 0), so the night vision effect is indifferent from the player without the effect in the dimensions). However, the extreme darkest saturated color that can be seen in the uniquely generated dimension with this status effect is blue within the value of exactly 0.0722 (as in an Easter egg dimension called blue).

Immune mobs

Withers and ender dragons are immune to Night Vision. All mobs are unaffected in behaviour by Night Vision in practice.

Trivia

Mobs are unaffected by Night Vision due to its purely visual effects. However, withers, ender dragons, and giants are completely immune to this effect. If submerged in lava, the screen appears bright orange. If in water in a swamp biome, the view is foggy and obscured.
