Is this possible?

colour = new Array();
colour[0] = new Color(_root.seven);
colour[1] = new Color(_root.work);
colour[2] = new Color(_root.bar);

can’t get her to work, what i want to do is have an array which contains all the colours so in a button and i can change a whole scheme with like

on (release) {
colour[2].setRGB(0x602100);
}

so is it possible?
