End result will be the PNG below, but when I use StringJoin to join Styled Characters, error pop up StringJoin::string: String expected at position 1 in StringJoin[M]. Possible issue is StringJoin works only with explicit strings, while TreeForm[Style["M",Red]] shows it is not a String and thus cannot use StringJoin, how could I make it?

Mia,

You have to convert the Style to a StandardForm String before StringJoin.

ToString[Style[#, RandomColor[], 30], StandardForm] & /@ Alphabet[] // StringJoin
