6 Choose one of the following
methods from the Using pop-up
menu:
• Paper produces a screen using
the paper grain. If the Papers
palette is open, you can choose
different textures while the
Apply Screen dialog is open.
• Image Luminance creates tex-
ture based on the image’s
brightness. It is similar to a
three-level posterization.
• Original Luminance adds tex-
ture based on the clone source
document’s brightness.
• [Alpha channel] or [Layer
mask] adds texture based on
the luminance of a channel or
layer mask. The pop-up menu
lists each alpha channel in the
document. If a layer with a
layer mask is selected, the layer
mask is also listed.

Color Overlay
Use the Color Overlay effect to
simultaneously add color and texture
to an image.
The Color Overlay effect.
The color is taken from the current
color on the Colors palette. Both color
and texture are applied using one of
five methods:
• Uniform Color adds a flat tint to
the image.
• Paper overlays a color using the
paper texture as a mapping model.
More color is applied to light areas
in the paper grain; less color is
applied to dark areas.
• Image Luminance uses the
image’s brightness as the model for
the color overlay. More of the effect
is applied to light areas in the
original image; less is applied to
darker areas.
• Original Luminance uses the
luminance of the clone source as
the model for the color overlay.
Light areas in the clone source
produce more color in the image.
• [Alpha channel] or [Layer mask]
uses the values in the channel or
layer mask as the model for the
color overlay. More color is applied
to the light areas of the channel or
mask, and less to dark areas.
You can use this method only if
you have a saved alpha channel or
a layer mask in your image.
