Channel Inversion
 |
 |
|---|---|
| Input | Result |
Inverts the image by inverting the channel values.
\[f(x) = 1-x\]White becomes black and vice versa. Hues are rotated 180° – red becomes cyan, green becomes magenta and blue becomes yellow.
Hue Inversion
|
 |
|---|---|
| Input | Result |
Point reflection / rotation of the colour wheel without inversion of the Lightness.
Lightness Inversion
|
 |
|---|---|
| Input | Result |
This inverts the image but keeps the hue.
It combines both operations of Channel Inversion and Hue Inversion in order to avoid the rotation of the colour wheel.
