This single large conjugatedsystem is a chromophore with strong absorption in visible spectrum, giving this compound its distinctive color. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. A conjugatedsystem has a region of overlapping p-orbitals, bridging the interjacent single bonds. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. A conjugatedsystem is formed where carbon atoms covalently bond with alternating single and double bonds; in other words these are chemical reactions of hydrocarbons.

From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Organic fluorophores fluoresce thanks to delocalized electrons which can jump a band and stabilize the energy absorbed, hence most fluorophores are conjugated systems.

The various shades result from different concentrations of halochromic molecules with different conjugated systems. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. As the number of conjugated double bonds increases, electrons associated with conjugated systems have more room to move, and require less energy to change states.
