Abstract
An image-editing application may be configured to transform a color hue value range in an image to a replacement color hue value range. The image-editing application may create a hue histogram of the image. The hue histogram may include tabulated frequencies of color hue values included in the image. The image-editing application may search for prominent peaks in the histogram. For a prominent peak, the image-editing application may determine a corresponding range of color hue values. Subsequently, the image-editing application may determine a range of replacement color hue values. The image-editing application may replace the prominent color hue values with the replacement color hue values. When the image is displayed on a display device, the pixels associated with the prominent color hue values will display the replacement color values.
