Besides injecting custom CSS using st.markdown with unsafe_allow_html=True is there a way to completely override the default palette?
The main reason why I am asking this is that if I simply inject some CSS to change the color of a particular element when the user interacts with this element the colors will default to the original palette.
The same happened when I tried to change the small gradient in the header.
Thanks for making Streamlit.
Hey @robsanna!
Currently there is not a way to override the default palette, BUT this is already being worked on by the team!!! 
In fact we are looking to release Theming, which has a planned release in this quarter!!
(We are already laying the ground work behind the scenes check out one of the latest releases)
Also, one of our fantastic creators members @Jesse_JCharis , has meda a youtube tutorial on how to make css changes in Streamlit, maybe this could be useful to you in the meantime?
Happy Streamlit-ing!
