How to change Select color, similar to Dropdown

Stylesheets usually are the best option, e.g.:

select = w.Select(
    value="Option 1",
    options=[
        "Option 1",
        "Option 2",
        "Option 3",
    ],
    stylesheets=[
        ".bk-input { background-color: #FFA500; }",
    ],
)

This will change the background of the <select> element within the component. If you want to change the background of the entire component, then use:

    stylesheets=[
        ":host { background-color: #FFA500; }",
    ],
