nonbright

Nonbright is an adjective meaning lacking brightness. It can describe light levels, colors, or surfaces that do not emit or reflect much light, such as a nonbright room, or a color with low visibility or saturation. It can also be used in a figurative sense to denote dullness or lack of vividness, but this figurative use is uncommon and may be considered pejorative when applied to a person.

Etymology and usage: The form derives from the negative prefix non- attached to bright. It is relatively rare in contemporary English. Many style guides prefer the separated form not bright or, when a compound is needed, the hyphenated non-bright. In older texts or in certain technical or stylistic traditions, you may encounter the closed form nonbright.

Context and clarity: Because brightness can refer to illumination, color, or metaphorical brightness (cleverness), the intended sense is usually clear from context. If precision is required, writers typically choose more specific terms such as dim, dull, low brightness, or low saturation rather than nonbright.
