{{FileDescription
|name_de=PALETTES.CFG.DAT
|filetype=palettes.cfg.dat
|version=March 2013
|version_descr=March 2013
|significance=contains the list of palette files which are currently available to the program [[NCPLOT]]
for the symbolization of data.

Each pallet file defines a color legend and assigns a unique name to it.

Example ''palette.dat'' for the color legend '''P_SEQ_PUR_09_Blues''': 
Color legend contains 9 blue tones
<nowiki>
BEGINDATA palette
Name = P_SEQ_PUR_09_Blues
Fill_Color = NONE
Lower_Color = White
Upper_Color = div_11_Bu_dark
Color_File = $PROGHOME/examples/lights/SP09/seq_pur_09_Blues.dat
ENDDATA palette
</nowiki>

The palette definition determines the colors for invalid data and the colors for the two
arrowheads attached at the ends of the legend.
The colors of the arrowheads are used to symbolize the values lying above and below
the value range the associated interval definition spans.
The attribute ''Color_File'' holds a reference to a file of type ''redef_colors.dat'',
which contains the definition of the color ramp.

Example ''redef_colors.dat'' for the color ramp '''seq_pur_09_Blues.dat''': 
<nowiki>
BEGINDATA redef_colors
# --| = |----------------------------------------------------------------------|
1 = seq_pur_09_Blues_01
2 = seq_pur_09_Blues_02
3 = seq_pur_09_Blues_03
4 = seq_pur_09_Blues_04
5 = seq_pur_09_Blues_05
6 = seq_pur_09_Blues_06
7 = seq_pur_09_Blues_07
8 = seq_pur_09_Blues_08
9 = seq_pur_09_Blues_09
ENDDATA redef_colors
</nowiki>

The colors mentioned in the two files must be defined in the file [[COLORS.CFG.DAT | colors.cfg.dat]].

The number of colors in the color ramp, selected for the symbolization of a layer, and the number of
intervals in the associated interval definition must match.

If no such file exists in the work directory, NCPLOT automatically accesses the predefined configuration
file ''palettes.cfg.dat'' in directory ''$PROGHOME/cfg/''.
It is recommended to use the file from the PROGHOME configuration directory, because it provides access to
all color palettes prepared by PROGHOME.

'''List of palette files'''
 

In PROGHOME area the definitions for a wide range of color palettes are stored.
Essentially these are the colors and color ramps which are recommended for the symbolization
of maps by the page [http://colorbrewer2.org ColorBrewer 2.0 - color advice for cartography].
The site offers a nice tool for testing the effects of colors.
 
Besides the BREWER color legends there are still some BAW own palettes prepared.

Overview and names of the palettes:
# [[Media:BREWER_SEQ_PUR.png|BREWER: monochromatic sequential color ramps]]
# [[Media:BREWER_SEQ_HUE.png|BREWER: multicolored sequential color ramps]]
# [[Media:BREWER_DIV.png|BREWER: divergent color ramps]]
# [[Media:BREWER_QUALITY.png|BREWER: qualitative color ramps]]
# [[Media:BREWER_COMBINED.png|BREWER: combined color ramps]]
# [[Media:BAW_eigene_Paletten.png|BAW: own color ramps]]

The BREWER provides sequential, diverging and qualitative color ramps.
The various ramp types are different well-suited for the display of a given physical size.
[[File:NcplotBspBestPals.png|thumb|250px|Picture 1: Particularly suitable color ramps.]]

* Sequential color ramps: Suitable whenever a very smooth ramp should reflect the variable intensity of a physical quantity. For example: Topography, salinity or magnitude of the flow velocity.
* Divergent color ramps: Suitable for zero-crossing such as differences or ratio values greater than / less than '''1'''. For example: Water level, differences, flood period : ebb period.
* Qualitative color ramps: Are particularly suitable when different classes are to be distinguished and the size of the data value is not important. For example:Grain diameter, sediment class.
The page [[PALETTES: Different Impressions of Color Ramps|Impressions of Color Ramps]] shows some examples.
 

'''Hint:''' 
It is recommended to use the predefined colors and color ramps.
This supports a corporate design.
The few palettes shown in graphic "[[Media:NcplotBspBestPals.png|Particularly suitable color ramps]]"
should be sufficient in most cases.

The colors and color ramps, which are defined in the PROGHOME area, are managed only from the PROGHOME staff. 
If necessary, each user can define and hold his own color ramps locally. 
That requires the creation of the following files:
* Files of type ''redef_colors.dat'' with the color ramp (see above).
* Files of type ''palette.dat'' with all the attributes of a color legend (see above).
* File of type ''palettes.cfg.dat'', list of the created palette files.
* If necessary file of type [[COLORS.CFG.DAT|colors.cfg.dat]], if you want to use your own colors.
