I just realised something.
Ib's main color is red and red means determination and anger. Determination to escape and anger from being betrayed by Mary.
Garry's main color is blue and blue means sadness and Integrity. Sadness because Ib has been trapped too and feels Integrity towards Ib.
Mary's main color is yellow and yellow means loneliness and justice. Loneliness because she was left alone with all those other painting stuff and justice towards her artist.
To me this who the Ib characters are in Undertale.
Ib= Frisk
Garry= Sans
Mary= Flowey (before Asriel, likethe souless mean Flowey)
If you disagree go ahead. But this is what it looks to ME.
