I have control_array.tex and 10 templateA.tex, templateB.tex, ... TeX files. In control_array.tex:

• ArrayName = [Name1,Name2,...Name10]


• ArrayColor = [Color1,Color2,...Color10]

With Array in control_array.tex I can change all variable only one time in all templates: templateA.tex, templateB.tex, ...

Here's my MWE:

documentclass[a4paper,twoside,12pt]article
usepackagexcolor
begindocument
%Call Name1, Nam10...Color 1, Color2...Color10
beginenumerate
item textcolorcolor1Name1
item textcolorcolor2Name2
item textcolorcolor3Name3
endenumerate
textcolorcolor4Name9 \
textcolorcolor5Name8
enddocument

How can I do it with LaTeX? Any ideas are welcome.

You could use pgffor for that.

documentclass[a4paper,twoside,12pt]article
usepackagepgffor
usepackagexcolor
begindocument
defArrayNames"koala","duck","marmot","penguin","bear"
defArrayColors"gray","yellow","blue","red","brown"
beginenumerate
foreach X in 0,...,4
pgfmathsetmacromynameArrayNames[X]
pgfmathsetmacromycolorArrayColors[X]
item textcolormycolormyname
endenumerate
enddocument

Or with an external file (which I create here for the convenience of others in the MWE, but you may drop the filecontents stuff as long you have a data file).

documentclass[a4paper,twoside,12pt]article
usepackagefilecontents
beginfilecontents*myarrays.tex
defArrayNames"koala","duck","marmot","penguin","bear"
defArrayColors"gray","yellow","blue","red","brown"
endfilecontents*
usepackagepgffor
usepackagexcolor
begindocument
inputmyarrays.tex
beginenumerate
foreach X in ArrayNames
foreach Y [count=Z starting from 0]in X 
pgfmathsetmacromycolorArrayColors[Z]
pgfmathsetmacromynameArrayNames[Z]
item textcolormycolormyname
endenumerate
enddocument

And of course you can install any mapping. Here is an example (in which I assume you already have created myarrays.tex, if not uncomment the corresponding lines).

documentclass[a4paper,twoside,12pt]article
% usepackagefilecontents
% beginfilecontents*myarrays.tex
% defArrayNames"koala","duck","marmot","penguin","bear"
% defArrayColors"gray","yellow","blue","red","brown"
% endfilecontents*
usepackagepgffor
usepackagexcolor
begindocument
inputmyarrays.tex
pgfkeys/pgf/declare function=mymap(x)=int(mod(1+x*x,4));
beginenumerate
foreach X in ArrayNames
foreach Y [count=Z starting from 0]in X 
pgfmathsetmacromycolorArrayColors[mymap(Z)]
pgfmathsetmacromynameArrayNames[Z]
item textcolormycolormyname
endenumerate
enddocument

As you can see, this function is chosen such that it distinguishes between birds on the one hand and mammals and beings on the other hand.

Trivial with listofitems.

documentclassarticle
usepackagelistofitems,xcolor
newcommandArrayNamesName1,Name2,N3,N4,N5,N6,N7,N8,N9,Name10
newcommandArrayColorsred,blue,cyan,cyan!50!red,red!50,
 purple,green,yellow,blue!50,magenta
readlist*arraynameArrayNames
readlist*arraycolorArrayColors
begindocument
beginenumerate
foreachitemxinarraynameitem textcolorarraycolor[xcnt]x
endenumerate

textcolorarraycolor[4]arrayname[9]

textcolorarraycolor[5]arrayname[8]
enddocument

You can have files with the following structure

colorlist
 red
 green
 blue
 green!40!yellow
 -green!40!yellow
 rgb:-green!40!yellow,3;green!40!yellow,2;red,1
 red>wheel,12

It would also be possible to have the simpler structure

red
green
blue
green!40!yellow

- green!40!yellow
rgb:-green!40!yellow,3;green!40!yellow,2;red,1
red>wheel,12

if preferred. Then in the document you call

assigncolors<filename><list of names for the colors>

Here's the code, using filecontents for making the example self-contained; the name for the color list file can be whatever you prefer.

beginfilecontentsjobname.colors
colorlist
 red
 green
 blue
 green!40!yellow
 -green!40!yellow
 rgb:-green!40!yellow,3;green!40!yellow,2;red,1
 red>wheel,12

endfilecontents

In a very simplistic way you can place a number of color definitions using (say) colorletcolorX<colour> inside color_array.tex and load them within the document preamble:

documentclassarticle

% Just for this example, create control_array.tex that contains all the colour definitions
usepackagefilecontents
beginfilecontents*control_array.tex
usepackagexcolor
colorletcolor1blue
colorletcolor2green
colorletcolor3red!30!yellow
colorletcolor4rgb:black,1;red,2;orange,3
colorletcolor5black!50
endfilecontents*

inputcontrol_array% Input colour definitions

begindocument

beginenumerate
 item textcolorcolor1Name1
 item textcolorcolor2Name2
 item textcolorcolor3Name3
endenumerate

textcolorcolor4Name9

textcolorcolor5Name8

enddocument

Note that inputcolor_array is called within the preamble since color_array.tex includes a call to load xcolor which can only be called within the preamble.
