[FMX] Need to change colour/format of multiple objects

I have a number of graphical called “Arms1”, “Arm”… “ArmsN”.

I would like to change the colour of all the objects.

I have a _global.armColour variable that I would like to access and all the graphics to change to that colour.

How do I great a for loop to create N number of these:

armsColor = new Color(_root.ArmsN);

and set N number of these.

armsColorN.setRGB(0x000099);

N = say 10.

Any ideas?
