PS Script - Change Layer Color

Question

This Is My First Post Here, So Hello Everyone,
Hope I Am Posting In The Right Section,
I Have A Photoshop File Which Looks Like Shown Above..
The Text 1 2 3 ...15 Are Different Layers..
And The Boxes Are Different Layers, Named i1 i2 i3 ...... i15
I Want To Write A Script That Will Change The Color Of Boxes (Actually This Is Legend Section For A Pie Chart)
I Want To Write Very Hard-Coded Script, Nothing Dynamic,
Like
layer[i1].color = #9f13a8
layer[i2].color = #520457
layer[i3].color = #cc626c
layer[i4].color = #aa5705
I Tried Searching Around, But Very Less Help Available On ps-script And Complicated Examples....
I Just Want Some Simple Lines, How To Easily Reference A Layer By Name And Change The Color (Forecolor, I Guess)
I Wrote This But It Does Not Works
var myDocument = app.activeDocument;
var myLayer;
myLayer=myDocument.artLayers.getByName("i1");
myLayer.color="#9f13a8";
I Don't Know If .artLayers Is Only For Text Layers Or Something.. I Found It In An Example...
Thanks

If you want to apply a pattern you can use scriptlistener to generate the code. It might be best to create the shape first by either drawing it or by using scriptlistener to generate the code, then use scriptlistener to generate code to change the fill pattern. This way you can use that code for any type of shape layer: oval, rectangle, etc. If you don't want a dialog box, you will have to find both the name and id number for the pattern used - again, this will show up using scriptlistener. If you want have a dialog box come up and be able to select which pattern you want to use, change the last line of the scriptlistener code to:
executeAction( idsetd, desc10, DialogModes.ALL );
But be sure to reset the dialog mode to No after that line. Here's an example of the code for changing a pattern:
#target photoshop
var idsetd = charIDToTypeID( "setd" );
    var desc10 = new ActionDescriptor();
    var idnull = charIDToTypeID( "null" );
        var ref2 = new ActionReference();
        var idcontentLayer = stringIDToTypeID( "contentLayer" );
        var idOrdn = charIDToTypeID( "Ordn" );
        var idTrgt = charIDToTypeID( "Trgt" );
        ref2.putEnumerated( idcontentLayer, idOrdn, idTrgt );
    desc10.putReference( idnull, ref2 );
    var idT = charIDToTypeID( "T  " );
        var desc11 = new ActionDescriptor();
        var idPtrn = charIDToTypeID( "Ptrn" );
            var desc12 = new ActionDescriptor();
            var idNm = charIDToTypeID( "Nm  " );
            desc12.putString( idNm, """$$$/Presets/Patterns/Patterns_pat/TieDye=Tie Dye""" );//pattern name
            var idIdnt = charIDToTypeID( "Idnt" );
            desc12.putString( idIdnt, """1b29876b-58b7-11d4-b895-a898787104c1""" );//pattern ID number
        var idPtrn = charIDToTypeID( "Ptrn" );
        desc11.putObject( idPtrn, idPtrn, desc12 );
    var idpatternLayer = stringIDToTypeID( "patternLayer" );
    desc10.putObject( idT, idpatternLayer, desc11 );
executeAction( idsetd, desc10, DialogModes.ALL );//Change the NO to ALL
app.displayDialogs = DialogModes.NO;//Make sure you reset!!!
