The problem seems to be here:
var hexNum:Number = parseInt(c, 16);
You're asking parseInt to convert a string to an integer and telling it the
string is an hexadecimal representation, when it's decimal, according to
this line:
trace("string colour:"+c); // e.g. for red: 16711680
So try,
hexNum:Number = parseInt(c,10);
If you have a number, you don't need to worry about decimal / hexadecimal.
It's just a number: you can have, say, the number 10, which would be
represented as "10" in decimal, "0xa" in hexadecimal, "1010" in binary, etc,
but those are just a way to display a number. If you already have the
number, you don't need any extra step.
Hope this helps.
