```php
MovieClip.prototype.nc = function(){
Math.round( Math.random()*0xFFFFFF );
myColoredObject = new Color (this);
myColoredObject.setRGB(myColor);
}
```
then i call the function by placing an action on the mc that says:
```php
onClipEvent(enterFrame){
nc();
}
```

lmao
genius beta … pure genius
right so now the code looks like this:
```php
MovieClip.prototype.nc = function(){
myColor = Math.round( Math.random()*0xFFFFFF );
myColoredObject = new Color (this);
myColoredObject.setRGB(myColor);
}
```
and it’s going skitzo … i’m guessing it’s b/c i tell the mc to do it on (enterFrame) but wheew … it’s changing color 15 times a second … lol
if i do on (load) then it will only set one color … i’d kinda like a transition … i don’t remember the code but a while back there was a code posted here for a random color that tweened itself from one color to the next.
do you remember what it was?

Try this…
```php
MovieClip.prototype.nc = function() {
red = Math.sin(ra += .02)*127+128;
green = Math.sin(rb += .05)*127+128;
blue = Math.sin(rc += .09)*127+128;
myCol = red << 16 | green << 8 | blue;
myColored = new Color(this);
myColored.setRGB(myCol);
};
```
