There are basically two aspects to the colorists job. He will provide a sense of color continuity throughout a scene by individually adjusting the colors and luminance to match the different shots. And, often working with the cinematographer, he can create an overall look and visual atmosphere for the film by adjusting the color palette and contrast. Apart from this its also often the colorist that controls the final image sharpness and grain. In the old days of film (...) the colorist was also called timer, and he used red, green and blue lights to adjust the colors and luminance of a film transfer. Apart from the lights the look of the images could also be affected by chemical processes like skip bleach or bleach bypass, to suppress certain colors, or increase the contrast. Nowadays, even material that was shot on film is often transferred to a digital format to allow for digital color grading, which allows for much more interactivity between the image and the colorist, and the possibilities are near endless, as long as the image quality allows.
