The quality or degree of being chromatic; the state of having or being rich in color.
From 'chromatic' + '-ness' (suffix for abstract qualities). A straightforward formation that appeared in English texts in the 18th-19th centuries as color theory developed.
While not super common, 'chromaticness' lets you talk about how colorful something is as an abstract property—useful when comparing paintings or describing why a piece feels vibrant or muted.
