type
tip
When adding a new layer, it is placed on the bottom of the stack and it is considered the foreground (FG).
The result of all layers above it is considered the background (BG). Layers are applied from the top to the bottom.
Where darker and lighter pixels are mentioned below, it is in relation to mid-grey.
Blend Mode
Description
Normal
Displays the current layer (FG) on top of all layers (BG) without blending. This is the default.
Average
The average of the current layer (FG) and the result from the layers below it (BG).
Add
Adds the FG to the BG.
Subtract
Subtracts the FG from the BG.
Darken
Compares the FG to the BG and takes the darker pixel values of the two.
Multiply
Multiplies the FG by the BG.
Color Burn
The color of the FG is applied to darker pixels in the BG.
Linear Burn
Same as Color Burn but with less contrast.
Lighten
Compares the FG to the BG and takes the lighter of the two.
Screen
Makes both light and dark areas lighter.
Color Dodge
The color of the FG is applied to lighter pixels in the BG.
Linear Dodge
Same as Color Dodge but with less contrast.
Spotlight
Same as Multiply, but with twice the brightness.
Spotlight Blend
Same as Spotlight, but additionally brightens the BG.
Overlay
Darker pixels become darker where the BG is dark and brighter pixels become brighter where the BG is bright.
Soft Light

Hard Light
Spotlight is applied to pixels where the FG is dark and Screen is applied to pixels where the FG is bright.
Pin Light
Replaces the BG colors depending on the brightness of the FG color. If the FG color is lighter than mid-gray, BG colors darker than the FG color are replaced and vice versa.
Hard Mix
Adds the FG to the BG and for each color component returns a value of 255 if the result is 255 or greater, or returns 0 if the result is less than 255.
Difference
Compares the pixels in the BG and FG and subtracts the darker pixels from the brighter ones.
Exclusion
Same as Difference but with less contrast.
Hue
Uses the hue from the FG , while the value and saturation are taken from the BG.
Saturation
Uses the saturation from the FG, while the value and hue are taken from the BG.
Color
Uses the hue and saturation from the FG, while the value is taken from the BG.
Value
Uses the value from the FG, while the hue and saturation are taken from the BG.
Opacity – Adjusts the transparency of the layer in 0 to 1 range, where 1 is fully opaque and 0 is fully transparent.
Bin icon () – Deletes the layer. This action is irrevocable.
Up/Down buttons () – Move the layer up or down in the stack.
