how to remove highlight color on toolbar ?

any ways to remove or change this higlight ? it doesnt looks good ive tried to change it in application color settingd but it doesnt change anything

Which Manjaro Xfce theme are you using (the name, not just “dark” / “white”), and which theme setting in LibreOffice? Most probably that highlight color is from the operating sytstems display manager theme and hence not configurable in LibreOffice.
