Color Correction tool
Color Wheel
The Color Wheel allows you to remove a color cast from an image.
Picker
The Picker lets you pick a known neutral gray shade in your image and 
adjusts it to a closer, truer gray. The grays in an image may have a 
particular color cast which can be verified through the color information in 
the Info window. A gray that tends towards a reddish tint, for instance, will 
have its R value skewed higher than the G and B values. By using the 
Picker on a gray area, the gray is adjusted so that the RGB values become 
approximately equal.
Angle
This shows the angle of the pointer on the Color Wheel as measured in 
degrees, and a value can also be entered directly in the edit box to move 
the cursor to any point in the Wheel.
Example: 0° corresponds to the color red on the Wheel, 60° to the color 
yellow, 120° to the color green, 180° to the color cyan, 240° to the color 
blue, and 300° to the color magenta.
