How can I change the colour of test in code blocks when generating pdf output?

[e05bf027]

Description

I am finishing a PhD thesis and writing the manuscript with Quarto to create a pdf. The work involves some coding, and this code is included as a few code blocks in the Appendix. The code displays with colour, and to save on printing costs, I want it to display as black and white. I can't seem to manage this but hopefully someone here can guide me.

I can't find any options that apply to the code chunks directly. My msot promising lead was to alter the YAML to state the following:

...
monofont: 'JetBrains Mono'
    monofontoptions: 
      - Scale=0.6
      - Color=black
...

I thought this would force the monofont used to render the code to display without colour, but it has not worked.

Anyone have any idea how I might do this?

Disable code highlighting or choose a black&white theme: https://quarto.org/docs/output-formats/pdf-basics.html#syntax-highlighting
