google maps color?

hi,

i use the following code for a custom google maps color:

.gm-style-iw div div {
color:black !important;
}

.gm-style .gm-style-iw { color: #00c472; }

.avia_google_maps_container img {
-webkit-filter: grayscale(100%);
-moz-filter: grayscale(100%);
-ms-filter: grayscale(100%);
-o-filter: grayscale(100%);
filter: grayscale(100%);

}

But this code works not on Internet explorer. Is there a solution for IE?

Thanks!
