### Description

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()](https://learnpython.strivemath.com/p5-python-web/reference/colour-and-outline/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()](https://learnpython.strivemath.com/p5-python-web/reference/colour-and-outline/colormode).
