Developing a stylesheet in JupyterBook and build it using latex pdf

[Radhika Saraf]

Hi, I wish to develop a stylesheet (cover page) for my latex document with a Title (colour Dark Green) and Author names (colour golden) and background colour as Green. I'm developing this in JupyterBook and building it by the following command:

Jupyter-book build bookname --/builder pdflatex.

Following is my _config.yml file:

title: /color{black!60!Green!70!blue} Digital Services

author: Radhika Saraf

Can anybody please help me to override the sphinx/jupyterbook configuration to get colours for author name and a background colour/background image?

Thanks!
