Colour centre in humans as an area specialized for colour vision. V2, also called the prestriate cortex, is believed to have a small role in colour processing by projecting signals from V1 to the V4-complex. Whether or not colour selective cells are present in V2 is still being investigated. Some optical imaging studies have found small clusters of red-green colour selective cells in V1 and V2, but not any blue-yellow colour selective cells. Other studies have shown that V2 is activated by colour stimuli, but not colour after images.[8] V4 also has feedback on V2, suggesting that there is a defined network
Light and Colour (Goethe's Theory) – The Morning after the Deluge – Moses Writing the Book of Genesis painting is a reference to Goethe’s "Theory of Colour", which explains the colour yellow as being the first colour transmitted from light. The form of the painting is circular, symbolising the construction of the human eye, changing the focus of a typical linear splitting of space to a more subjective portrayal. The colour yellow is typically optimistic, but Turner captures the negativity of yellow by attaching the colour to a light that is subject to change. The morning sun aspect of the colour is something transient. "Light and Colour" was among three paintings stolen from a Frankfurt museum in 1994.
