How do I change theme to lighter for Google Maps using Maplace.js plugin

I've created google map with custom marker icons using maplace.js plugin.

icons looks properly but the problem is, on the darker google map, icons doesn't look good.

Javascript Code 开发者_JAVA技巧for Map:

    <script>  
    let obj = JSON.parse('{{data|escapejs}}')
    map_data = []
    for(i in obj){
        let block = `<div>
                        <h6>${obj[i]["Route_Id"]}</h6>
                        <p>Shipping Types : ${obj[i]["Shipping Type Code"]}</p>
                        <p>Product Type : ${obj[i]["Product_Type"]}</p>
                    </div>`
        let icons = obj[i]["icon"].replace('000000', obj[i]['Color'])
        console.log("icon : ",icons);
        let jsn = {"lat":obj[i]["lat"], "lon":obj[i]["lon"], "title":obj[i]["Route_Id"], "html":block, "icon":icons}
        map_data.push(jsn)
      
//create Map Object
    new Maplace({
            locations: map_data,
            controls_on_map: false,
        }).ViewOnMap().Load();
    </script>

So I wanted to change darker google map theme to light google map.
