Almost there. G# major/minor's going to be interesting because I don't quite have a good handle on a chord I rarely if ever have heard or used.
If you read what I have below about major/minor differences on the previous posts, go ahead and skip this - it's just for newcomers reading this.
A note on major/minor:
There is an obvious difference between a major and a minor. Wikipedia naturally describes a minor chord has differing "from a major chord in having a minor third above the root instead of a major third." In other words, the third key from the first on a keyboard (not in the chord or scale) would simply be moved a key to the left. In C major, the notes are C-E-G. E is three keys from C; move one key to the left and you're now on E flat or D sharp. Hence C minor. The "minor third" just means the third note in a minor scale.
Ear-wise, the difference is also obvious because minor chords sound darker and moody and tentative while major chords are bright and happy and powerful in contrast. If you've heard any sad songs, they're likely built around a minor scale progression and use minor chords. 'Not Home Today' uses mostly minor chords (E minor and B minor) and is a song about an unfortunate circumstance, with a doom-filled ending. 'Around the Bend' uses largely major chords and is a happy song about friendship and good times. Of course, not all songs operate this way - 'The Sign' by Ace of Base has bright chords yet talks about a potentially negative relationship. 'Alive' by Pearl Jam has what people have referred to as an anthemic sound, with great strong major guitar chords and progressions, yet it's about a man who discovers his father died long ago and his mother is virtually attracted to him thanks to his resemblance to his father.
The thing about inversions - where the root note is not the lowest or first note played in the chord - is that it's all the same for every chord major or minor: It's either darker or brighter, in terms of colour as well as personality (though slightly, and it's perhaps more on the main personalities' view or opinion or feeling on something).
Spatial Direction: Like just about all the others, east.
This is the one chord (both major and minor) that kind of stumps me, because I never hear it often in music - the most I've ever heard of it is as the third or fourth note in a progression, which makes it a sort of subdominant or final sound in that context, but otherwise, I've almost never used it on the keyboard. I've heard F# major and minor and A# major/minor quite a few times, but never the lone G#, stuck in the middle between both of them.
If I could say anything, G# major is probably the guy who doesn't have any complaints or comments of note, positive or not. He doesn't know what to do with his life. He just blindly takes whatever comes to him and goes with the flow. Nothing really interests him, but nothing really gets his disapproval either. Probably a younger person without much life experience, or a drifter-type. The guy who takes whatever crap comes to him with a "oh well, it is what it is" attitude. This is different from the negative version of this saying, which would be applied to life in general, not the mere circumstance.
This is the last guitar chord played in the progression of the song 'I Can't Stop' by jackSoul, and the second chord played in the 'Ah! Leah!' chorus.
Colour: Deep gold, like fries well-cooked.
Light: Muted (I think that area of the keyboard is largely muted).
Spatial Direction: East, southeast.
In going through the other chords on the keyboard, I've come up with at least two chords who are kind of similar - like A and B major, or C and D major, D# and E major to an extent. G# minor is similar to C minor. Both are worriers.
The difference is that G# minor is not the type of worrier who worries about getting things done or getting anywhere or what people think of him. He worries about getting into sticky situations, because while he is mild-mannered and low-key and kind, he tends to be accident-prone and stuck in a position that involves delivering bad news. He could be an unconfident tax person come to tell someone they're being audited or something. And he hates confrontation, doesn't deal with it well. He'll worry that an angry person whom he just served with an audit will jump him from behind at the bus stop or subway and push him in front of the bus or train. He's not really paranoid, but while he tries to maintain a positive, good demeanor, his lack of confidence - compounded with his accident-prone manner - causes him to sometimes feel scared and as a result pity himself on his worst days. He's not a bad guy - he doesn't focus on the negative - but he just lacks confidence and certain fine motor skills and dexterity owing to falling off his bike all the time or spilling coffee on himself (picture Andy Dick as Matthew from News Radio but not as extreme). This chord is the third one in the piano progression of 'All That She Wants' by Ace of Base.
One more to go - A# major/minor.
