colors
An array of ColorReplaceCommandColor classes that provides information about the replacement color used by this class.
hue
Angular amount to change the hue, in hundredths of degrees. Valid values range from -18000 to 18000. This value is divided internally by 100.
saturation
Amount to change saturation, in tenths of a percent. Valid values range from -1000 to 1000. This value is divided internally by 10. Negative values decrease the saturation of colors. Positive values increase the saturation. The saturation level is increased or decreased by a percentage of its present saturation level. For example, an increase of 20 of the current saturation level "L" will raise the new saturation level "L1" to a value L = 0.20 * L. Likewise, increasing the saturation level 100 doubles the saturation level (L1 = L + 1.0 * L). Decreasing the saturation level 100 will set the new saturation level to 0. The saturation is set to 1000 (maximum value) if the new value exceeds 1000).
brightness
Amount to change the brightness, in tenths of a percent. Valid values range from -1000 to 1000. This value is divided internally by 10. Positive values increase (or lighten) the brightness of the image. Negative values decrease (or darken) the brightness of the image.
Run the ColorReplaceCommand on an image to change the red color by rotating its hue 90 degree.
