About blending modes
When you select a blending mode, Fireworks applies it to the selected objects in their entirety. Objects in a single document or on a single layer can have blending modes that differ from those of other objects in the document or on the layer.
When objects with different blending modes are grouped, the group's blending mode overrides individual blending modes. Ungrouping the objects restores each object's individual blending mode.
Elements in a blending mode:
Blend color:
The color to which the blending mode is applied.
Opacity:
The degree of transparency to which the blending mode is applied.
Base color:
The color of pixels underneath the blend color.
Result color:
The result of the blending mode's effect on the base color.
Applies no blending mode.
Dissolve:
Randomly chooses colors between the current and background layer to create the blend effect.
Darken:
Selects the darker of the blend color and base color to use as the result color. This mode replaces only pixels that are lighter than the blend color.
Multiply:
Multiplies the base color by the blend color, resulting in darker colors.
Color Burn:
Darkens the base color in each channel to reflect the blend color by increasing the contrast. Blending with white produces no change.
