Change accordion active icon color

I’ve tried a variety of recommendations from the support forum, but I’ve not found a way to change the accordion icon color on my site. I’d like the active accordion icon color to be white. Here’s a link to screenshot to be sure that I’m asking you for the correct info: https://ibb.co/kxwLGJ

Here’s what I currently have in Quick CSS…

.toggler {
color: #804223 !important;
background-color: #f7f7f7 !important;
}
.toggler.activeTitle {
background: #804223!important;
color: white!important;
}
.active_tc .toggle_content {
background: white!important;
}
.toggle_icon .vert_icon, .toggle_icon .hor_icon, span.toggle_icon {
border: none!important;
}
.toggle_icon * {
border: none!important;
}
.toggler .toggle_icon:before {
content: ‘ ▸’;
color: #2c2c2c;
position: relative;
top: -8px;
}
.toggler.activeTitle .toggle_icon:before {
content: ‘▾’;
color: #white !important;
}
