Yellow colour along bottom of barrel cactus, is it sick?

I've noticed recently that my barrel cactus (which I believe is a Ferrocactus Histrix) seems to have acquired a discoloration in a ring around its bottom, from about 1 cm above the surface of the soil down. Whereas the rest of my cactus is a dark green, this area is a very light green going on yellow colour. I do not remember noticing this on my cactus before, making we worried as to what could have caused it or if its normal
For some context, it is winter where I live now (Sydney, Australia). My cactus sits on the window sill indoors, getting about 3+ hours of direct sunlight and maybe 4+ hours of indirect/reflected/shaded sunlight each day. I try to water it infrequently, especially since the winter started, but I can't be sure if I've given it too much or not. Any advise on this issue would be greatly appreciated!
