I agree that the Tools guide could be a lot more helpful than it is. Most of the time when I am trying something new with ScriptUI I end up going in hyperlink circles until I give up.
And it doesn't help that once you do get something working in one version on one OS, it doesn't work the same in a different version or OS.
colorselector.jsx is in both the ESTK and Bridge SDK. For what it's worth it seems to work the same in CS3 and CS4. Here is the CS3 version script. At a quick glance it is the same in the CS4 SDKs

@fileoverview Shows how to use graphic objects to customize the drawing of ScriptUI elements.
@class Shows how to use graphic objects to customize the drawing of ScriptUI elements.
<h4>Usage</h4>
<ol>
<li> Open this file and run it in the ExtendScript Toolkit.
You can choose as the target any application that supports ScriptUI, although we recommend Adobe Bridge CS3.
<li> Move the sliders up and down to change the color of the top panel.
</ol>
<h4>Description</h4>
<p>Changes the colors of ScriptUI components dynamically, using the graphics customization objects.
Displays sliders that allow the user to set the RGB components of a color, then
creates new Pen and Brush types using those colors with methods of the ScriptUIGraphics objects
associated with the window and panels.
<p>To make the change in how the colors are drawn into the window on the screen, the example places the
new Pen and Brush objects into the appropriate color properties of the graphics objects. The Pen is
used to change the foreground, and the Brush is used to change the background.
<p>Each Pen and Brush object is created with a brush type, a color value, and a line width.
The color is given as an array of RGB values with a fourth number representing the Alpha
channel (transparency) value. The range for all values is 0 to 1.
For example, to set the background color of a window to a light grey:
<pre>
graphicsObject.backgroundColor = graphicsObject.newBrush (g.PenType.SOLID_COLOR, [0.75, 0.75, 0.75, 1], 1);
</pre>

/**
<p>Functional part of this snippet, creates a Window and its ScriptUI components.
Defines three panels: an instruction panel, a panel that displays the current
color values, and a control panel.
<p>The control panel contains radio buttons to choose the background or
foreground, and sliders to choose new color values. As the sliders move,
their event handlers apply the new colors to the background or foreground
of the window. The event handlers use a helper function, changeColor(), which actually
performs the color change, by creating Pen and Brush objects and using them to set
the color properties of the graphics objects associated with the window and with
each panel.
