A handy function I wrote that calculates a color value between two colors.

function getColor(fromColor:uint, toColor:uint, scale:Number):uint {
    var red:uint = ((fromColor >> 16) + (toColor >> 16) - (fromColor >> 16) * scale) << 16;
    var green:uint = ((fromColor >> 8 & 255) + ((toColor >> 8 & 255) - (fromColor >> 8 & 255)) * scale) << 8;
    var blue:uint = (fromColor & 255) + ((toColor & 255) - (fromColor & 255)) * scale;
 
    return red + green + blue;
}
