In case anyone else might be intrested, I fixed this color problem using these codes:
.category-1 , .category-70 , .category-120 {
.category-children-item .fa-caret-right {
color: #ff9800 !important ;
}
}
.category-111 {
.category-children-item .fa-caret-right {
color: #e91e63 !important ;
}
}
.category-2 , .category-77 , .category-78 , .category-126 , .category-127 , .category-132 , .category-93 , .category-115 {
.category-children-item .fa-caret-right {
color: #4caf50 !important ;
}
}
Basically I had to name each category separately... So, if there is any suggestion to shorten the code, I would love to hear...
