Changing st.chat_message("assistant") font color

[Roger1]

I have been able to use the below to make the font as the size i want. But there are still responses from the bot giving me green color. May I know how do I get rid of it??

I using an external pacakage called pandasai to generate results.

st.markdown(
    """
    <style>
    [data-testid="stChatMessageContent"] p{
        font-size: 1.75rem;
    }
    </style>
    """, unsafe_allow_html=True
)

I think i would like to change this green to another color. But I am not sure what varaible should I change though.
