Yes. The old version had "from Int" twice. The "from"s and "to"s don't actually go together, it can simply be cast from a load of things, and cast to a load of things. Adding the from UInt makes it possible to do this:
```
var myUint:UInt = 0xff123456;
var myColor:FlxColor = myUInt; // Not previously allowed
FlxColor.interpolated(myColor, myUInt); // Not previously allowed
```
