__NOTOC__
=Overview=
Slicer offers a variety of predefined lookup tables (LUT). Volumes can be associated with a LUT in the volumes module. Also, see the [[Documentation/{{documentation/version}}/Modules/Colors|Colors Module]].

==LUTs for Charting==
Please see the [[Slicer4:2012_GenericChartColors|Generic Chart Colors]] page.

==LUTs in Slicer==
You can review and edit LUTs in Slicer via the [[Documentation/{{documentation/version}}/Modules/Colors|Colors module]]. 
=Slicer ColorPicker=
The slicer colorpicker allows to select colors from a label map and to assign them to objects such as surface models or streamlines.

==Custom LUTs==
It is relatively easy to create custom LUTs by creating a table with the colors on the wiki. This allows to select specific names and colors when segmenting. See below for an example.

{| class="wikitable sortable labelpage labelpagetable" border="1"
! integer_label
! text_label
! color
! notes
|-
|0
|background
|style="background:rgb(0,0,0);color:white"|rgba(0,0,0,0)
|
|-
|1
|tissue
|style="background:rgb(128,174,128)"|rgb(128,174,128)
| Default label for bodily tissues
|-
|2
|bone
|style="background:rgb(241,214,145)"|rgb(241,214,145)
|
|-
|3
|skin
|style="background:rgb(177,122,101)"|rgb(177,122,101)
|
|-
|4
|connective tissue
|style="background:rgb(111,184,210)"|rgb(111,184,210)
|
|-

* Standard color names and values: http://www.w3.org/TR/SVG/types.html#ColorKeywords
* Go [http://labelpage.halle.us/ here] to create a text file in Slicer LUT format.
* A custom LUT can be loaded into Slicer like any other file.
