Adjustments to contrast, gamma, gain, and offset often comprise the bulk of the work in color correction. Some artists prefer to makes these adjustments via sliders; others prefer curves (which represent the range of color values in an image.) Nuke’s ColorCorrect and ColorLookup nodes offer tools to suit either preference.
