värvimolekule
Värvimolekule are molecules that impart color to materials. They operate by absorbing specific wavelengths of light and reflecting the remaining wavelengths, with the reflected spectrum defining the observed color. Most värvimolekule feature conjugated systems—such as aromatic rings or alternating double bonds—that enable electron delocalization, shifting their absorption into the visible light range.
Natural examples include indigo (a blue plant-derived dye), while synthetic varieties like azo dyes dominate textiles
