What does chromatic mean?
Chromatic is an adjective with two principal meanings: one relating to colour, and one relating to music. In its everyday sense, it describes anything connected with colour, particularly in a rich, varied, or vivid way — a chromatic palette, chromatic effects in photography. In its musical sense, it refers to notes or passages that move in semitones rather than following the steps of a conventional major or minor scale; a chromatic scale includes all twelve pitches within an octave. The word derives from the Greek 'chrōma', meaning colour, which also gives us words such as chromosome, monochrome, and polychrome. Chromatic appears most often in formal or technical writing about art, design, optics, and music theory, though it can lend descriptive flair to general prose as well. Understanding it helps readers navigate both visual and musical vocabulary, since the same term bridges these two domains.
Relating to or characterised by colour, especially vivid or varied colour.
"The designer favoured bold chromatic contrasts throughout the collection."
(Music) Relating to or employing notes that fall outside a standard major or minor scale, moving by semitones.
"Bach's chromatic harmonies pushed well beyond the conventions of his era."
In music theory this sense is contrasted explicitly with 'diatonic', which describes music confined to the notes of a given key.
The word 'chromatic' shares its ancient Greek root with 'chromosome' — because chromosomes were named for how readily they absorb coloured dyes under a microscope.

Etymology of chromatic
Chromatic comes from the Greek 'chrōmatikos', derived from 'chrōma' (genitive 'chrōmatos'), meaning colour or skin. It entered English in the early seventeenth century, initially in learned and scientific contexts, and later developed its distinct musical sense describing intervals smaller than a tone. Cognates from the same Greek root include chromosome, coined in the late nineteenth century for structures that stain readily with coloured dyes, alongside monochrome and polychrome.

How chromatic is actually used
Chromatic is a moderately formal word, most at home in discussions of art, design, optics, and music. Its two main senses — relating to colour and relating to non-diatonic musical intervals — are distinct enough that context usually makes clear which is meant. The comparative and superlative forms (more/most chromatic) exist but are uncommon; the adverb 'chromatically' is rare and largely technical.
Easily confused with chromatic
