(That's just one, look thru that doc for more. I'd also like using the 
green and yellow tones from there.)

Ah, very good. You're absolutely right.

Do you mean literals? Centered in the rectangle also, I think.

I don't understand. I am thinking, interface::

    Color getBgColor();
    void setBgColor(Color c);

    boolean getDrawBorder();
    void setDrawBorder(boolean b);

and abstract implementation::

    protected Color bgColor;
    protected boolean drawBorder;

    public Color getBgColor() { return bgColor; }
    public void setBgColor(Color c) { bgColor = c; }

    public boolean getDrawBorder() { return drawBorder; }
    public void setDrawBorder(boolean b) { drawBorder = b; }

I.e., the normal Java pattern.

Re-read my last sentence :-)
