Colors in Matplotlib

Named colors can be specified by using a single character enclosed in quotes. For example, line_color = "r".

The named colors are:

b: blue
g: green
r: red
c: cyan
m: magenta
y: yellow
k: black
w: white

Other named colors can be seen illustrated here.

A RGB color can be specified in hexadecimal format as line_color = "#eeefff"
