hi,
I do that. create a child theme: create a new folder in themes, call it hiero-child
copy style.css in this news folder
change the first part of the file (from the beginning till global) with this
/*
Theme Name: My Hiero Child
Template: hiero
*/
@import url(“../hiero/style.css”);
then edit the file looking for color and changing only the #xxxxxx value
