    variable::Int
    quoted::Int
    keyword::Int

    call::Int
    macrocall::Int
    op::Int
end

The default color is the Monakai256:

function Monokai256()
    return ColorScheme(;
        symbol=141,
        type=141,
        variable=141,
        quoted=141,
        keyword=197,
        number=141,
        string=185,
        comment=240,
        line=240,
        call=81,
        macrocall=81,
        op=197,
