Why does a drink's color change how it tastes?

Before the first sip lands on your tongue, your eyes have already decided what it tastes like.

Color sets an expectation - red and pink hint at sweet, green hints at sour - and your brain blends that expectation into the flavor you actually perceive. Dye a drink the wrong color and people will even name the wrong flavor.

Pour the same orange juice into a clear glass and a dull grey one, and the grey-glass juice tastes flatter - your eyes tasted it first.

Flavor is not just on your tongue. The color you see quietly steers how sweet or sour the same food seems.

Knowing color drives taste, you can read past it: a vivid drink is not really sweeter, and a dull-looking dish is not really blander.

Red light means sweet, green light means sour - your eyes flip the switch before your tongue votes.
