The colour centre is a region in the human brain responsible for processing colour. It consists of two subdivisions, an anterior one, called V4α and a posterior one, called V4. The structural organization of the colour centre was analysed using fMRI.

Functional magnetic resonance imaging (fMRI) is the use of MRI to measure the hemodynamic response related to neural activity in the brain or spinal cord of humans or other animals. ...

The term colour centre can also refer to an anionic vacancy in a crystal filled by one or more electrons, usually called an F-Centre. An F-Center, from the German Farbenzentrum, is the anionic vacancy in a crystal filled by one or more electrons (depending on the charge of the missing ion in the crystal). ...
