Hi,

I’m trying to convert 0xcolour into colour using toString(16). The problem I’ve got is it’s not adding the zeroes in front of the number.

here is the code

[AS]var aColours:Array=new Array(0x000000,0x0000FF,0xFF0000,0x009933,0xFFFFFF);

for (var i = 0; i\<aColours.length; i++) {  
trace(aColours\*.toString(16));  
}  
[/AS]

This is what I get back

```auto
0
ff
ff0000
9933
ffffff

```
