Hello Community,
I need help on following situation:
I have created multiple text area types with dynamic shapes fill as shown below image the situation. I have prepared custom colors group and want to randomize all these selected dynamic shapes within created colors group.
is that possible with any trick or script

@j.khakase Thanks for your sample files.
Unfortunately, the scripting API doesn't provide access to anything but the very most basic appearance, eg. a fill color and a stroke color. Because in your example file you use a more complex appearance (two fills and a live effect nested in a fill), a script won't really help here.
One solution would be to simplify the artwork—eg. split the artwork into a basic colored rectangle plus a point text frame. This would make a scripting approach feasible. See the attached demo file and try it with the script below. Note: this is just a demonstration—your exact needs will probably require something more specialized.

Everytime you run script it will apply a random color from the same color group.
Can select multiple page items:
/**
* @file Change Fill Color By Color Group Random Swatch.js
*
* Experiment of applying swatch to the selected items,
* where the swatch is chosen at random from amongst the
* item's fill color's parent swatch group.

var doc = app.activeDocument,
items = doc.selection;
if (0 === item.length)
return alert('Please select one or more page items and try again.');
for (var i = 0; i < items.length; i++)
applyRandomColorGroupColor(doc, items[i]);
})();
