Using Controls in the Color Picker
You can adjust the controls in the Color Picker in the following ways:
To choose a color from the ColorWheel:
m Drag the pointer in the wheel to select a point.
Crosshairs make it easy to spot the precise color that’s chosen, and the four sampling
controls above the ColorWheel reflect the selection.
To change the overall value of the wheel and the selected color:
m Drag in the luminance bar underneath the ColorWheel.
The overall brightness of the ColorWheel changes.
To sample color from the Viewer:
m Drag over the image in the Viewer.
The ColorWheel and color sampling swatches above the ColorWheel automatically
update as you drag in the Viewer.
The color swatches sample pixels from the image in four different ways:
• Current: Samples the exact color value of the last pixel you clicked or dragged over.
• Average: Samples the average color value of all the pixels you drag over.
• Min: Samples the minimum color value of all the pixels you drag over.
• Max: Samples the maximum color value of all the pixels you drag over.
