Set the fill colour of a vector shape?

Is it possible to set the fill colour and/or stroke colour of a vector shape in the currently selected layer with a script?

I'd use it in a similar way to the one I had help with before at this forum, by using a colour copied previously to the clipboard (in RGB Hex format) and applying that colour to the vector shape.

Here's the script I'm using to grab the colour from the clipboard and use when adding the colour overlay layer style, in case it helps understanding what I want to achieve with the new script:

set colourFromClipboard to the clipboard
tell application id "com.adobe.Photoshop"
  set docRef to the current document
  try
  tell docRef
  do javascript "var c = new SolidColor();    
  
c.rgb.hexValue = " & quoted form of colourFromClipboard & " 
  
app.activeDocument.suspendHistory('TMP', 'aaa()');      
executeAction( charIDToTypeID( 'undo' ), undefined, DialogModes.NO );    
executeAction( charIDToTypeID( 'PaFX' ), undefined, DialogModes.NO );    
    
function aaa()    
    {    
    app.activeDocument.artLayers.add();
