Why does a carnation flower absorb the red color the fastest?

Carnation flowers absorb red color the fastest due to their specific pigment composition and structure. The pigments, primarily anthocyanins, are adept at absorbing light in the red spectrum, which allows them to reflect and transmit other colors, contributing to their vivid appearance. Additionally, the flower's cellular structure facilitates the quick uptake of pigments, enhancing their ability to absorb red wavelengths efficiently. This combination of pigments and structure results in a pronounced absorption of red light.
