Dissolve: The result color is the blend color just like Normal, but as you modify the opacity of the blend layer, blend-layer pixels are removed, so you get a speckled effect nothing like Normal.

Multiply: The result color is the base color multiplied by the blend color, creating a darker color. Multiplying by black always results in black. Multiplying by white doesn't change the color. Like felt pens, each stroke deepens the color if the blend color is anything but black and white.

Screen: The result color is always lighter after multiplying the inverse of the blend and base colors. So black leaves the color unchanged while white always results in white. Think of "screening" in this context like a screen door: blocking stuff (like black flies) out.

Overlay: The result color is either Multiplied or Screened, depending on the base color. Dark base colors are Multiplied and light base colors are Screened, preserving the base highlights and shadows.

Soft Light: The result color is a lighter base color if the blend color is lighter than 50 percent gray and a darker one if it is darker. If the blend color is black or white, it only darkens or lightens the base color.

Hard Light: Like soft light, except a black blend color can end up a black result color and a white blend color can paint white. Handy for adding either shadows or highlights to an image.

Color Dodge: Brightens the base color to reflect the blend color.

Color Burn: Darkens the base color to reflect the blend color.

Darken: The result color is the darker of the base or blend colors.

Lighten: The result color is the lighter of the base and blend colors.

Difference: The result color is what's left when the brighter color is subtracted from the darker color, regardless of layer. If the blend color is white, the base color is inverted. If it's black, the base color is unchanged.

Exclusion: The result color is slightly lower contrast but similar to Difference.

Hue: The result color has the hue of the blend color and the luminance and saturation of the base color. Hue only.

Saturation: The result color has the saturation of the blend color but the hue and luminance of the base color. Saturation only.

Color: The result color has the luminance of the base color with the hue and saturation of the blend color. Gray levels are preserved while allowing them to be tinted, as in a hand-painted black-and-white image. Hue and saturation.

Luminosity: The result color has the hue and saturation of the base color but the brightness of the blend color. Brightness only.
