AS3 Getting colours blended between two other colours

Here is another function that can be added to my ColourUtil class. This one gets a specified number of colour steps between two blended colours.

I thought it would be much harder to achieve than it is, luckily the AS3 Color class has the static method interpolateColor which calculates a single colour at a specified position using a ratio value.

The function below is a simplified version of the function found at AS3 Adventure. This blog post also has a much better explanation of the interpolateColor method, and a great demo of the function.

function getColoursBetween(colour1:uint, colour2:uint, steps:int):Array
{
    var arr = [],
        i:uint,
        ratio:Number;

    arr.push(colour1);

    for (i = 1; i < steps; i++)
    {
        ratio = i / steps;
        arr.push(Color.interpolateColor(colour1, colour2, ratio)); 
    }

    arr.push(colour2); 
    return arr; 
}
