What unit is used to express the clarity of a display in terms of colors?

The correct answer is the color gamut, which is a measure that defines the range of colors a display can reproduce. It indicates the spectrum of colors that can be displayed, typically expressed as a portion of a color space, such as sRGB, Adobe RGB, or DCI-P3. A wider color gamut means that the display can showcase more colors, leading to more vibrant and accurate representations of images, which enhances the clarity and realism of visuals.

Understanding color gamut is crucial for tasks that require color precision, such as graphic design or photography, where accurate color reproduction matters significantly. A display with a good color gamut allows for a more immersive viewing experience.

Screen resolution refers to the number of pixels on the screen and primarily affects image detail rather than color quality. Pixel density is related to resolution too, measuring how many pixels are present per unit area and can influence sharpness but does not directly correlate with the clarity of colors. Refresh rate indicates how many times per second a new image is displayed on the screen, impacting motion smoothness but not the ability to reproduce colors accurately. Each of these options relates to display quality in some way, but only the color gamut specifically addresses the clarity of a display in terms of the range of colors it can show.
