When using rings=c(col='all') then every column value gets annotated and there's a legend to explain which color corresponds to which value. If we instead annotate a column by a specific value, there's no legend: rings=c(col='some_val'). This becomes particularly troublesome when we annotate specific values in multiple columns because then we don't know which ring corresponds to what.
