gamutot

Gamutot is a fictional unit of measurement used in discussions of color space and perceptual color reproduction. Within the imagined framework, a gamutot quantifies the amount of perceptual color information required to reproduce a color within a given display system, normalized to a standard observer and illumination. It provides a scalar for comparing the gamut capacity of devices or color spaces independent of device-specific metrics.

Etymology and origin: The term blends “gamut” with a suffix that evokes a small unit, and it was coined in speculative fiction and pedagogical essays to explore the limits of color representation. It is not an official SI unit and has no standard definition in real-world color science.

Usage: In fictional or teaching contexts, gamutots serve to illustrate relative color capacity. For example, a device with a larger gamut might be described as having a higher gamutot value under the same lighting than a device with a smaller gamut.

Relationship to conventional concepts: Gamutot is distinct from measurements such as color gamut area, bit depth, or Delta E. It is intended as an abstract, comparative metric rather than a precise physical quantity. In serious color engineering, standard metrics based on CIE color spaces and perceptual differences are used.
