Smell and taste of colors...

Red
It would taste like brick and ashes.
It would smell of beer or other alcohols.

Blue
It would have a cold flavor, like mint with blueberry and ice.
It would smell like clean rain or freshly turned-on air conditioning. Yes, the smell of "cold." The brain does strange things.

Green
It would taste of green apple, lemon, and fresh grass.
It would smell like a forest after it rained.

Yellow
It would definitely taste like mango, pineapple, or sour candy.
It would smell of citrus and sunshine. Don't ask what sunshine smells like. Your mind already knows.

Purple
It tastes of grape, plum and something mysterious, like dark chocolate.
Scent of sweet perfume and night-blooming flowers.

Orange
It would literally taste like oranges… because humanity never got over giving things simple names.
It would smell of citrus peel and chili-flavored sweets.

Black
Intense flavor, like bitter coffee or sweet charcoal.
It would smell of smoke, rain, and old books.

White
It would taste like milk, vanilla, and snow.
It would smell like clean soap and cotton.

Pink
Cotton candy and strawberry bubblegum flavor.
It would smell of soft perfume and flowers.
