Obviously, things like taste and nutritional value are important when eating food (as well as perhaps texture), but one thing that I think is also important is the color of the food.
For example, I wouldn't eat meat that's been colored blue, green, or purple. I am fine with sweet foods (like cookies and ice cream) that have those colors, though.
I'm not a cookie person,but for the food...first of all,for me the taste matters and the colour of it,is the result on what condiments i'm using when i'm cooking.
I've never understood the weird hair colors, either. Unless it's for Halloween. I've never seen pink, blue, green, purple, orange, or candy-apple-red hair look good on anybody.
It has been proven by scientific experiments that color is very important to taste. People were served food under lights which made steak look green, and peas black, and they got sick.
Personally I try to avoid eating or drinking anything which is blue.
I remember a line from the series As Time Goes By. Jean and Lionel are having dinner at Penny and Steven's. While Penny's in the kitchen helping Steven make coffee, Lionel asks Jean why Penny's gravy is always gray. I've always wondered what would make it gray. Off the top of my head, I can't think of any food that is naturally gray. I've seen meat look gray when it's going bad, but otherwise nothing.
I generally like foods to be the colors they naturally are , at their peak of ripeness or freshness. Off-colors in nature are a clue that the food has spoiled or is not safe to eat. That's why people don't like green steak- because green meat would be meat that has spoiled and will make you violently ill.
The reason we make a mental exception for cookies and candy, is that these type of food are not found in nature so they don't have a natural color. And usually they use a color that mimics the flavor it is supposed to be. We get a lot of flavor cues from the color.
My late mother had killed all her taste buds (and sense of smell) from a lifetime of smoking, so she really couldn't taste much. One time for Christmas I made some vanilla cookies but colored them red and green to look prettier on the platter. She took a green one and asked "is this mint?" I said no, it's vanilla. She took a bite and said "are you sure it's not mint? it's green." She didn't taste or smell any mint but her brain was expecting mint because of the color.
Thanks R.
An interesting experiment is make some different flavored candy but color it the 'wrong' color, and see if people can correctly identify the flavor. Like a grape flavored candy that is yellow- can anyone taste the grape with that wrong color clue, or will their brain tell them it's lemon or banana?
Or just make them all white.
There are even people who insist the different colored m&ms are different flavors.
