== Description ==
[[SelectiveColour]] - AviSynth implementation of Photoshop's selective colour adjustment.
 
 
== Requirements ==
* [x86]: [[AviSynth+]] or [https://sourceforge.net/projects/avisynth2/ AviSynth 2.5.8 or greater]
* Supported color formats: [[RGB32]]
 
== [[Script variables|Syntax and Parameters]] ==
:{{Template:FuncDef|selectivecolour (clip, float, float, float, float, float, float, float, float, float, float, float, float, float, float, float, float, float, float, bool)}}
 
::{{Par2| |clip| }}
:::Input clip; must be RGB32.
 
::{{Par2| |float| }}
:::This filter partially copies the actions of Photoshop's "Selective colour" image adjustment action. Apart from an input clip it takes 19 arguments.
:::The first 18 are floats in the range -1 to 1 (other values are accepted, but that behaviour is not well defined).
:::These are in groups of three, representing the Cyan, Magenta, and Yellow %ages (normalized) present in Photoshop's Selective Color dialogue for each of the six colour sections (reds, yellows, greens, cyans, blues, magentas).
 
::{{Par2| |bool| }}
:::Boolean to choose either relative (false) or absolute (true) mode, as per the Photoshop dialogue box.
 
== Examples ==
Usage:

[[AviSource]]("blah.avi")
ConvertToRGB32()
selectivecolour(last,\
0.5,0,0,\
0.25,0.1,0,\
1,-0.5,-0.25,\
-0.5,0.5,-0.5,\
0.1,0.2,0.3,\
-0.1,-0.2,-0.3,\
true)
 
The six triples act on the following sets of pixels (a pixel may be a member of up to 2 adjacent sets):

*Reds: those pixels where R>G and B
*Yellows: R and G>B
*Greens: G>R and B
*Cyans: G and B>R
*Blues: B>R and G
*Magentas: R and B>G

The first number in a triple alters the Red channel, the second the Green channel, the third the Blue channel. Because Photoshop calls these values Cyan, Magenta and Yellow, the numbers work backwards - if you want to increase the intensity of a channel, use a negative number, and vice versa.

The filter doesn't currently implement the "Black" value in Photoshop.
