'dark-themed' originates from the combination of 'dark' and 'theme', where 'dark' refers to a lack of light and 'theme' refers to a subject or style.

The term 'dark-themed' evolved from the use of 'dark' to describe low-light environments and 'theme' to denote a consistent style or motif.

Initially, 'dark' meant 'lacking light', and 'theme' meant 'subject or style'. Over time, 'dark-themed' came to specifically refer to designs with a predominantly dark color scheme.
