hi,
The only theorietcial basis for keys sounding different is that in todays music we almost exclusively use the Well Tempered Scale, which is a compromise between physics and being able to design and play an instrument - it means that some notes are closer to the ideal in some keys than in others, making different keys sound ever so slightly different.
I can definitley understand feelings anc characteristics from the different major modes, but personally, different feelings from different major keys whilst present are so slight that I wouldn’t spend the time writing a list like the one above!
