Above, the Photoshop combined hue and tone controls

Corel Photo-Paint: Image/Adjust/Colour Hue OR Image/Adjust/Colour Tone

Adobe Photoshop: Image/Adjust/Variations

These adjust the colour or tone of the image in set amounts each time you click the small preview window. The slider control varies the amount that is applied each time and the radio buttons dictate which areas of the image are affected. Particularly good for removing any colour cast a photo might have.
