Color Adjustments

Color Adjustments are made cumulatively. Undo levels apply strictly to the selected control.
	Percent of brightness for each color channel (red, green, blue) separately or locked together. Values from -1 to -100 make the image darker, those from 1 to 100 make it brighter. For true color images the function is applied to pixels, for 8-bit images the function is applied to the palette (color map).
	Percent of contrast for red, green and blue channel separately or locked together. Negative values will decrease the contrast (colors will shift towards gray) while positive values will increase it. For true color images the function is applied to pixels, for 8-bit images the function is applied to the palette (color map).
	Gamma correction values for each color channel (red, green, blue) separately or locked together. Values below 1000 make the image darker; values above 1000 make it brighter. For true color images the function is applied to pixels, for 8-bit images the function is applied to the palette (color map).
	Percent of saturation from -100 to 100. Positive values make the colors richer, while negative reduce the amount of color in the image. A value of -100 removes all color information and produces a grayscale image. For true color images the function is applied to pixels, for 8-bit images the function is applied to the palette (color map).
	White balance is a name given to a system of color correction to deal with differing lighting conditions. Photos taken under florescent lighting is greenish; sunlight, more blue; incandescent light, yellowish. For true color images the function is applied to pixels, for 8-bit images the function is applied to the palette (color map).
	Solarization reverses some of the tones of (a negative or print) and introduce pronounced outlines of highlights. For true color images the function is applied to pixels, for 8-bit images the function is applied to the palette (color map).
