INFP = maybe a pastel pink to violet. Very very pale purple?
INFJ = Either royal blue or a very deep orange.
INTJ = Charcoal or deep brown.
ENFP = Yellow (mustard or sunset...)
ENTP = Pale blue
Kind of reviving this thread, I have always thought of assigning mbti types a specific color, I actually worked out something big a while I go,but I don't remember what I did exactly, so I came up with this:
I don't have a lot of experience with different personality types in that I have a clear impression of each one. I just don't type people very well. I do think of INFJs as a soft blue-green, kind of like being underwater. A soothing shifting of illusive color.
ENTPs I see as more vibrant, like an orange.
INFPs I see as a muddy purple
INFJs maybe as a deep brown, INFPs as perhaps a deep, natural green, something that exudes naturalness and serenity.
ESTPs as a loud/neon orange. something that is poppy and screams for attention...
