If your system is a surface (slab), you can use the menu "Tools-->Color
Scheme", and play with the "Slab colors" options, because in this case
you probably want to highlight atoms lying in plane parallel to xy
plane. Otherwise, if the plane of interest is not one of xy, xz, or yz
then you edit the structure file (i.e. XSF file), and replace atoms of
interest with some other "atomic species", and then you color these
"other" atomic species accordingly (Modify-->Atomic color).
