javascript - Best way to create a color picker gui in extendscript? -

i started out scripting in javascript , knowledge minimal.

i have few lines of code in create solid want gui color picker prompt user can choose color. here example below:

var mycomp = app.project.item(1); //points comp  var mysolid = mycomp.layers.addsolid([10,10,10],"shape", 10, 10, 1.0); // creates 10 pixel shape 

one of first parameters addsolid color enter array value identified in rgb values. wondering if can on ride value variable attached color picker gui? there objects or methods inside extendscript utility can create color picker? wondering.

i hope question clear. thank you

colorpicker(number color)
invokes platform-specific color selection dialog, , returns selected color.
parameters number color color preselected in dialog, 0xrrggbb, or -1 platform default.

var color = $.colorpicker(); alert(color); 

edit1:

ae uses colors in 4 value array values 0 1 [r, g, b, a] solid can not have alpha value.
