Chromophores almost always arise in one of two forms: conjugated pi systems and metal complexes. In our case, the chromophore is a conjugated pi-bond system. In this type of chromophores, the electrons jump between energy levels that are extended pi orbitals, created by a series of alternating single and double bonds, often in aromatic systems.<ref>http://www.chemguide.co.uk/analysis/uvvisible/theory.html#top</ref>. | Chromophores almost always arise in one of two forms: conjugated pi systems and metal complexes.

The residues surrounding the Venus chromophore are similar to those surrounding the chromophore of EYFP. Electron density studies of Venus show an 11° angle between the planes of the chromophore and Tyr203, while the same angle measured in EYFP is 11.5–12.3°, making the plane of the Venus chromophore slightly more parallel than that of EYFP. | The residues surrounding the Venus <scene name='Sandbox_206/Chromophore/1'> chromophore </scene> are similar to those surrounding the chromophore of EYFP.
