The following example shows how you can change the Button control’s borderColor and themeColor properties to one of the special Flex “halo” colors (”haloBlue”, “haloGreen”, “haloOrange” or “haloSilver”). Note that you can also use any other named or hex color as well, such as “red” or 0xFF0000.

what are the hex number for the haloColors?
Jacob P,
haloBlue = #009DFF
haloGreen = #80FF4D
haloOrange = #FFB600
haloSilver = #AECAD9
You can convert other named colors to hex values using the following:
<?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"> <mx:Script> <![CDATA[ import mx.controls.Label; private function getHex(evt:Event):void { var lbl:Label = evt.currentTarget as Label; lbl.text += "#" + ("000000" + lbl.getStyle("color").toString(16)).substr(-6).toUpperCase(); } ]]> </mx:Script> <mx:Label id="haloBlueLabel" text="haloBlue = " color="haloBlue" initialize="getHex(event);" /> <mx:Label id="haloGreenLabel" text="haloGreen = " color="haloGreen" initialize="getHex(event);" /> <mx:Label id="haloOrangeLabel" text="haloOrange = " color="haloOrange" initialize="getHex(event);" /> <mx:Label id="haloSilverLabel" text="haloSilver = " color="haloSilver" initialize="getHex(event);" /> </mx:Application>Peter
