Another umpteenth hypershift changing color question - Cynosa Chroma

Hi everyone, OK... I already know that there are other threads where this is asked but my question is a little different ... I have been buying a cynosa chroma for a couple of days and I am satisfied with my purchase From what I understand by default the "fn" button is set as hypershift key and that it is not possible to change colors when pressed ... Right? So I ask the first question: why then switch off the light of entire keyboard when pressing "fn"? I mean ... it's a contradiction! if I set in color set for my configuration why if i pressing "fn" all gone? If I can't choose the color to show when I press "fn" why not leave everything light on? visually it's easier to recognize the keys to which macros are assigned, don't you think? so ... is there a way to prevent all keys from turning off when i press hypershift? I already know that by configuring another key like "fn" this thing does not happen but I don't want to sacrifice a key when, in reality, I already have one that cannot be configured! Sorry for my english...
