Blending Modes

Blending modes are a little difficult to explain. Basically, when one layer is above the other, the computer uses a bit of programming to decide how the combination of both layers will look.

Blending modes can not just apply to Layers, but also to individual strokes.

Normal

Let's start explaining with the Normal Blending mode: As you may have guessed this is the default Blending mode for all layers.

In this mode, the computer checks on the upper layer how transparent a pixel is, which colour it is, and then mixes the colour of the upper layer with the lower layer measured by transparency.

Arithmetic

These blending modes are based on simple maths.

Addition

Adds the numerical values of two colours together:

Yellow(1,1,0)+Blue(0,0,1)=White(1,1,1)

Red(1,0,0)+Grey(0.5,0.5,0.5)=Pink(1,0.5,0.5)

Divide

Divides the numerical value from the lower color by the upper color.


Inverse Substract

???

Multiply

Multiplies the two colors with each other, but does not go beyond the upper limit.

White(1,1,1)xWhite(1,1,1)=White(1,1,1) White(1,1,1)xGrey(0.5,0.5,0.5)=Grey(0.5,0.5,0.5) Grey(0.5,0.5,0.5)xGrey(0.5,0.5,0.5)=Dark grey(0.25,0.25,0.25)

Substract

White(1,1,1)-White(1,1,1)=Black(0,0,0) White(1,1,1)-Grey(0.5,0.5,0.5)=Grey(0.5,0.5,0.5) Grey(0.5,0.5,0.5)-Grey(0.5,0.5,0.5)=Black(0,0,0)
