Using Shapes and Masks
Opacity Over Stroke: An opacity control that appears when Stroke Color Mode is set
to Use Brush Color. Use it to change the opacity of dabs based on their location on
the stroke. This gradient control is limited to grayscale values, which are used to
represent varying levels of transparency. White represents solid dabs, progressively
darker levels of gray represent decreasing opacity, and black represents complete
transparency. A simple white to black gradient represents a stroke that is solid at its
start, but that fades out gradually over its length until finally vanishing at the end.
For information on using the Gradient editor, see “
Use the gradient preset pop-up menu to load a custom opacity gradient into the
gradient editor.
Note: None of the default gradients have opacity gradients. If a color gradient preset is
selected, it has no effect on the opacity gradient.
 Color Over Stroke: The second option in the Stroke Color Mode pop-menu. Dabs are
tinted based on their position over the paint stroke. A gradient editor defines the
range of color of the stroke, beginning with the leftmost color in the gradient, and
progressing through the range of colors until reaching the rightmost color at the end
of the stroke. Gradual color changes do not appear in each dab, only across the
stroke as a whole. An opacity bar appears at the top of the gradient editor. For
