If you’re using the Color Configuration to scan, you can adjust a group
of color settings. Gamma controls the brightness of the color midtones.
Saturation is the strength or purity of a color and hue is the color your
eyes see as reflected from the image.
The following figure shows the color options.
To adjust the color settings:
1. Drag the Gamma, Saturation, and Color Hue sliders to the left to
decrease the settings or to the right to increase the settings.
You can also type a number directly into the setting boxes, or click
the up and down arrows next to the boxes.
2. Click Reset to return the settings to their original numbers.
