Docs: Restore my original header color (for light theme)

[blaylockbk]

The new PyData Sphinx dark theme is awesome! But how do I restore the header color? The header banner background is now white instead of tan

https://pydata-sphinx-theme.readthedocs.io/en/stable/user_guide/customizing.html?highlight=css#customize-the-css-of-light-and-dark-themes

This didn't seem to help:

.bd-header[data-theme="light"] {
    background-color: #f0ead2 !important;
}

a:-webkit-any-link[data-theme="light"] {
    color: #25529b !important;
}
