Only show sub-category color in icon?

Did a bit of digging so sorry if I missed this somewhere in my searches, but is there any easy way to prevent the category color from showing next to the sub-category color?

Would be ideal to have just one color rather than the two-tone split - the colors all look great on their own, but not so much when next to the category’s green.

Gonna run this live as soon as our owner is online again, but I think this should do what we want:

.badge-wrapper.bullet .badge-category-parent-bg {
    width: 0px;
    margin-right: 0;
}

.badge-wrapper.bullet .badge-category-parent-bg + .badge-category-bg {
    width: 9px;
}
