The Hue area allows the user to set the color hue range to map to and from. The bars displayed span values of 0 (zero) to 359 degrees, representing the cyclic nature of hue color values. A numeric value for each slider can be keyed in to the field to the right.

• The slider above the From Hue Range bar selects the start of the color range that will be mapped.
• The slider below the From Hue Range bar selects the end of the color range to be mapped.
• The slider above the To Hue Range bar selects the start point for the color range you'll be mapping to. Because the value range is cyclic, the selected area can wrap around to the left side of the bar.

The range of colors that is excluded by your selection is grayed out, allowing for a visual assessment of the selected range.

The lightness slider allows you to boost the lightness of colors across a range of (negative) - 100% to 100%. If the slider is increased above zero, colors will tend towards white. If the slider is set below zero, colors will move towards black. A numeric value for the slider can be entered into the field to the right.

Applies the lightness setting to only those colors that will be remapped. Leaving the box unchecked allows the lightness to be adjusted for every color.

The saturation slider allows you to boost the saturation of color across a range of (negative) -100% to 100%. If the slider is increased above 0, colors will tend towards primary colors. If the slider is set below zero, colors will move towards grayscale. A numeric value for the slider can be entered into the field to the right.
