"""Theme designed for friendly [friendly-traceback]
This theme has colours chosen for a light (white) background.
friendly uses Pygments themes mostly through
Rich [https://github.com/willmcgugan/rich].
Rich's console has styles for some objects that are defined
independently from a chosen Pygments theme.
In this file, we define a consistent theme which results
in the same colour shown for a certain object type whether
the colouring is done by Pygments or directly by Rich.
