Why do you think are blueberries not bright blue?
user
Blueberries are not bright blue because their pigment molecules have a unique structure that reflects light in a way that makes the berries look dark purple or maroon, rather than bright blue. The presence of tannins, which are brown colored compounds also decreases the bright blues in their color. Additionally, due to the fact that blueberries contain both anthocyanins (which can appear red or violet) and chlorophyll (which is green), they typically take on a mottled brownish purple hue.

Blueberries are not bright blue because the intense blue pigment in the berries, known as anthocyanin, is diluted by other pigments and sugars that are present. This dilution results in a softer, more muted hue. Additionally, the skinned hull of the berry absorbs some of the bright blues which further dilutes their hue.
