Why do dye molecules absorb light and how does this process contribute to their coloration?

Dye molecules absorb light because of their chemical structure, which allows them to interact with specific wavelengths of light. When light is absorbed by a dye molecule, it excites the electrons within the molecule, causing them to jump to a higher energy state. This absorption of light energy leads to the dye molecule appearing colored to our eyes, as the remaining light that is not absorbed is reflected or transmitted, giving the dye its characteristic color.
