How to slowly change object color from one to another?

Question

I am trying to achieve a scenario where the color of an object changes slowly from one color to another color.

I have the initial color as targetColor and final col

Answer 1

In order to achieve the act of slowness, it might be a good idea to use the instance of Robot class.

//Method to obtain the offset of the color

static int [] getColorOffset(Color initial, Color final){
    int [] colorOffset = new int[3];
    colorOffset[0]= final.getRed()-initial.getRed();
    colorOffset[1] = final.getGreen()-initial.getGreen();
    colorOffset[2]= final.getBlue()-initial.getBlue();
    return colorOffset;
}

updateColor(int [] colorOffset) throws AWTException{
    int  dr = colorOffset[0];
    int  dg = colorOffset[1];
    int  db = colorOffset[2];
    Robot slow = new Robot();
    int i=0;
    while(i<=10){
        slow.delay(1000)
        //sleep will sleep for 1000ms

        setColor(targetColor.getRed() + dr/10, targetColor.getGreen(),targetColor.getBlue());
        setColor(targetColor.getRed(), targetColor.getGreen() + (dg/10),targetColor.getBlue());
        setColor(targetColor.getRed(), targetColor.getGreen(),targetColor.getBlue() + db/10);

        i++;
    }

}

public static void main(String args[]) throws AWTException{
    Color initial = Color.black;
    Color final = Color,white;
    int [] colorOffset = getColorOffset(initial, final);
    updateColor(colorOffset);
}
