I've done that as well - I don't think it's weird at all to use a color to describe a taste, as color is one of many aspects of a sensation for me.
I can recall tasting something and describing it as "purple". My friends were confused, because what I actually meant was that the flavor reminded me of artificial grape flavoring, and those things tend to be purple in color.
It's funny because my mind doesn't associate artificial grape flavoring with the flavor of a real grape or grape juice, since the flavor of real grape is so much more complex, so it associates that artificial flavor primarily with just the color purple.
Purple Kool-Aid, purple Flavor Ice, purple Gobstoppers, they all taste like purple to me!
Everytime I drink Guinness, or any other strong stout, the sensation of "black" is appearing in my mind, probably because of the color that it is, and also associating it with other black things like black coffee or motor oil.
Its funny you bring this up because I am Hawaiian and we are big on rice, but it has to be "REAL" rice. My brothers and sisters dont do "FAKE" or instant rice because its not real rice. Its like they have associated the chinese type of rice as "REAL" rice and everything else is a knock off and not worthy. To me I have different types of rice and I like what they call "FAKE" rice just as much as "REAL" rice. Its different, but different is not bad, its just different.
With me I dont associate anything vaguely. Purple kool-aid gets its own distinction as purple kool-aid because it tastes different then purple gatorade. I cant group these together because they dont belong together. I like to try things and if I were to group things like that I would not be able to distinguish between all the different things in life. To my dad things are in life for a purpose, maybe thats what you mean by intention. Food is to eat, to make the hunger go away. He is very simple in that sense. Its like he has to have a goal to do something. Maybe thats what you mean by an objects intention. The intention things sounds like my ISTJ dad. On the outside me and him are alot alike, but we have never been able to really agree verbally on things. We have different thought patterns, but when we have a common goal we compliment each other because we have different ways of looking at things. Its almost like we cover all angles and one always gives in to the other when their idea is better without any fights. Complexity scares my dad while simplicity bores me.
I go back to socionics and relations and I think I am starting to understand the connection between ENFJ and ISTJ. If ENFJ has trouble finding the intention and ISTJ categorize things by purpose. Its like both line up because of vague categorization. The things you deem as simple line up with each other. You are better able to use J and make a decision because of lack of complexity. Where a P type is more complex but we suck at making a decision and pushing through because of the complexity.
I am not saying one is better than the other, just different. Both have there good and bad qualities.
