A system and method for effectively performing a white balance operation preferably includes an electronic camera device that captures image data using a image sensor device. A color manager may then analyze the image data to selectively locate one or more neutral areas in the image data. The color manager may analyze the neutral areas to determine one or more associated color values, and then responsively produce one or more composite color values for the image data by utilizing the individual color values of the neutral areas. From the foregoing composite color values, the color manager may derive one or more color correction values which the camera device may then apply to color channel amplifiers of the camera device to complete the white balance operation. However, if no neutral areas are located in the image data, the color manager may then analyze the image data to selectively locate one or more memory color areas in the image data. The color manager may analyze a memory color area to determine one or more memory color values corresponding to the memory color area. The color manager may then utilize the memory color values of the memory color area to reference a color table to thereby locate known memory color values for a closest matching known memory color. By substituting the known memory color values from the color table for the original memory color values of the memory color area, the color manager may derive one or more color correction values which the camera device may then apply to color channel amplifiers of the camera device to complete the white balance operation.
