Color Correction tool

This tool changes hue and saturation of the image. The Color Correction tool

lets you click on the preview image to remove the unwanted color cast. The

parameters needed to balance the clicked pixel is reflected on the color wheel,

angle and radius values are updated accordingly.

The Color Correction tool is useful when the image has a particular color cast

and you wish to remove the cast to make the image look neutral.

Color Wheel

The Color Wheel shows you the position of colors — green is across magenta,

and red is across cyan. By moving the pointer (a small dot in the center of the

wheel) to another place in the color wheel, the hue of the image is altered. For

instance, if you move the pointer towards the green area of the wheel, the image

will acquire a greenish cast.

Saturation bar

The Saturation bar lets you change the intensity of the hues (colors) in your

image. Use Saturation selectively, because increasing saturation will intensify all

hues in the image.

Picker

The Picker lets you pick up a color from the Preview image, and make this color

to closer gray.
