On a serious note...
I have forgotten my A320 stuff, but still remember the new Do328 Jet with PWC engines churning out Fadec Minor ( Blue) Info only
Fadec Major ( Amber) action dependent on other indications and ECAM
And Fadec Fault= Shut it Down ( anything can happen ie overspeed , idle or fail.)
Mind you this was in 2000 and I would hope Airbus is a bit more advanced then my respected Dornier friends.
Was it blue with no ECAM action needed and nothing in the QRH, If so a maintenance distraction.
A heads up that there might be something more coming ,,
Sorry, Now I am just making things up.
