Umbra

The umbra refers to the darkest, central part of a shadow where the light source is completely blocked. This intense darkness results from an opaque object intercepting light rays. It's a region of complete shadow, distinct from the penumbra, where the light source is only partially obscured, leading to a less intense, fading shadow. The concept of an umbra applies not only to visual shadows but also extends to metaphorical usages concerning darkness, secrecy, and obscurity, like in the 'shadow' of fear or grief.
