Immediately, we can tell the font is different, besides the title, the color of labels are grey, and the axis background is a light grey. Most lines in Matplotlib are drawn with the lines class, including the ones that display the data and those setting area boundaries. It is similar to a scatter plot except that the measurement points are ordered (usually by x-axis value) and joined with straight line segments. You can use any colour of red, green, blue, cyan, magenta, yellow, white or black just by using the first character of the colour name in lower case (use "k" for black, as "b" means blue).
