Changes the color of the border of all following shapes or lines, until another stroke() is called. Shapes have borders and interiors - stroke() changes the border, while fill() changes the interior. Input can either be the name of an HTML color, a value 0 - 255 for greyscale values with 0 being black and 255 being white. Input can also be three numbers for the RGB or HSB color scale - see colorMode().
