What does means blue, green, light blue notes colors in Key Editor when you using Chord Track?

I’m using Cubase 10 Pro, added Chord Track, deactivated Automatic Scales, set A Harmonic Minor… and can’t understand what does means blue, green, light blue notes colors in Key Editor when are you using Chord Track?

Green notes are within the chord. Blue notes are in key, but not in the chord. Not sure about light blue. Maybe it’s the same as red notes from this video. Scroll to 2:45 in this clip.

Thanks a lot!

Light blue is in the chord but not the key - lotta dicey 7ths hang out here. Red is not in chord or key. And green is both in the chord & key.

Thanks!
