Dear Aradhna
 

chromophore is the section of a molecule that causes us to see color. The chromophore portion of the molecule will have alternating double bonds, or conjugated double bonds. For example, beta-carotene, the molecule responsible for the color in carrots, has many double bonds. It absorbs light at approximately 455 nm (blue), so it appears orange.

As the number of double bonds increases, the wavelength of light absorbed by the molecule also increases
