A "Colourist" (more often colorist, due to the predominance of Americans in the industry) is the person who adds colour to images that have been pencilled and inked, usually by other artists. Though traditionally done with physical media, colouring is now mostly done digitally. Modern approaches narrow the gap between what a film colourist and a comic colourist do. Additionally, modern tools give the comic colourist a power with lighting panels that is not unlike that of a cinematographer. If the penciller and inker are mostly in charge of depicting what happens in each panel, the modern colourist creates the mood, not by simply adding colour, but also by adding textures, layers and lighting effects.
