Blend the colors between two overlapping objects by using blending modes. Blending modes let you vary the ways in which the colors of stacked
objects blend.
1. Select one or more objects or a group.
2. Do one of the following:
In the Effects panel, choose a blending mode, such as Normal or Overlay, from the menu.
In the Transparency area of the Effects dialog box, choose a blending mode from the menu.
Blending mode options
The blending modes control how the base color, the underlying color in the artwork, interacts with the blend color, the color of the selected object
or group of objects. The resulting color is the color resulting from the blend.
Colors the selection with the blend color, without interaction with the base color. This is the default mode.
Multiplies the base color by the blend color. The resulting color is always a darker color. Multiplying any color with black produces black.
Multiplying any color with white leaves the color unchanged. The effect is similar to drawing on a page with multiple magic markers.
Multiplies the inverse of the blend and base colors. The resulting color is always a lighter color. Screening with black leaves the color
unchanged. Screening with white produces white. The effect is similar to projecting multiple slide images on top of each other.
Multiplies or screens the colors, depending on the base color. Patterns or colors overlay the existing artwork, preserving the highlights
and shadows of the base color while mixing in the blend color to reflect the lightness or darkness of the original color.
Darkens or lightens the colors, depending on the blend color. The effect is similar to shining a diffused spotlight on the artwork.
If the blend color (light source) is lighter than 50% gray, the artwork is lightened, as if it were dodged. If the blend color is darker than 50% gray,
the artwork is darkened, as if it were burned in. Painting with pure black or white produces a distinctly darker or lighter area, but does not result in
pure black or white.
Multiplies or screens the colors, depending on the blend color. The effect is similar to shining a harsh spotlight on the artwork.
If the blend color (light source) is lighter than 50% gray, the artwork is lightened, as if it were screened. This is useful for adding highlights to
artwork. If the blend color is darker than 50% gray, the artwork is darkened, as if it were multiplied. This is useful for adding shadows to artwork.
Painting with pure black or white results in pure black or white.
Brightens the base color to reflect the blend color. Blending with black produces no change.
