Adjust the hue, saturation, or brightness of a color
1. In Motion, apply a Hue/Saturation Curves filter, as described in the previous task.
2. In the Filters Inspector, click the eyedropper for the curve that you want to use:
• Hue vs Hue: Changes the color (hue) of any range of hues in the image.
• Hue vs Sat: Changes the saturation of any hue in the image.
• Hue vs Luma: Changes the brightness of any hue in the image.
3. In the canvas, click or drag over the color in the image that you want to adjust.
Dragging increases the range of color selected.
Three control points appear on the curve in the Filters Inspector. The control point with
the vertical line represents the color you selected with the eyedropper. Two additional
control points represent a buffer range of adjacent hues that were also selected (to
ensure a more natural gradient of selected color). In the following image, the orange
control point represents the color selected with the eyedropper, and the green and
magenta control points represent adjacent hues on the color spectrum.
In the above image, notice that red hues appear on the left side of the graph and on
the right side of the graph. This is because the hue curve wraps around the graph,
representing the spectrum of colors.
Note: You can also create control points by clicking the curve, but the eyedropper method is
generally more precise. To delete a control point, select the point, then press the Delete key.
