Android Build a Simple Android App (2014) Improving Our Code Adding More Colors

Why can't I use Integer.parseInt(color) to set background color?

So I tried another approach for setting the background:

        public void onClick(View v) {
            String fact = mFactBook.getFact();


            //update the label with our dynamic fact
            factLabel.setText(fact);

            String color = mColorWheel.getColor();
            relativeLayout.setBackgroundColor(Integer.parseInt(color));

        }

The app crashed when I try to get new fact (and change background)

Getting error:

java.lang.NumberFormatException: Invalid int: "#51b46d"

Just curious why this doesn't work? Shouldn't the Integer.parseInt convert String to int?
