1 Press on the menu Window.
2 Select the option Design Panels → Color Swatches, if there were a tick besides the Panel name that would mean that it is already open. Otherwise, click on it.
3 Now select the green of this panel, you can see that if you put near the arrow it will turn into eyedropper tool (that should be used to select a color).
4 From this point onwards all that we draw will be color green (we can use this mechanism to change the filling or the color of line).
