error highlighting background color makes text hard to read in org with emacs-jupyter

[martibosch]

I am using zenburn theme in my setup: https://github.com/martibosch/snakemacs

When jupyter code blocks in Python in org mode raise errors, the background highlighting makes the error text almost impossible to read, e.g.,

#+begin_src jupyter-python
def foo(text):
    raise ValueError(text)

foo("can you read me?")
#+end_src

shows the following:

would there be any way of changing such colors? Thank you. Best,
Martí
