How to increase RGB values of a radial gradient of shapes every 1 or 3 frames?

Question

Hello everybody. I really need help. Indeed, i would like to inrease the RGB values of my radial gradient of my shape every 1 or 3 frames. I did it manually, but its very long. So i would like to know if anyone can help me to make it with code, it's will be most efficient and fast. I've already created my shape with a radial gradient. Now i would like just to increase the RGB values of my radial gradient. Can you help me please!
This code create my shape with a radial gradient:
var radType:String = GradientType.RADIAL;
var radMatrix:Matrix = new Matrix();
radMatrix.createGradientBox(120,120);
var tabCouleurs:Array = [0xFFFFFF, 0xAEAEAE];
var radColours:Array = tabCouleurs;
var radAlphas:Array = [1, 1];
var radRatios:Array = [0, 255];
var gradients:Sprite = new Sprite();
gradients.graphics.beginGradientFill(radType, radColours, radAlphas, radRatios,radMatrix);
gradients.graphics.drawRect(0, 0, 120, 120);
gradients.x = 50;
gradients.y = 50;
addChild(gradients);

Not really sure what you mean by increase RGB values. But if that is what you want to do then that is what you need to do.
clear() your graphics
increase the values
redraw
Nothing particularly difficult there. What is the problem you are having?
