The Slave Ship at the event, to see it and be moved to increase British anti-slavery efforts. Placed next to the painting were lines from Turner's own untitled poem, written in 1812: The first impression that the painting creates is of an enormous deep-red sunset over a stormy sea, an indication of an approaching typhoon. Upon closer inspection one can discern a ship sailing off into the distance. The masts of the ship are red, matching the blood-red colour of the sky and the sickly copper colour of the water, which serves to blur the lines between various objects in the painting. The
Colour centre the recognition of shapes, motion, and colour. V1 has multiple areas that are colour-sensitive, which indicates that colour processing is not limited to one area. According to a paper by Dr Robert Shapley, V1 has an important role in colour perception. fMRI experimental results showed that V1 has two kinds of colour sensitive neurons: single-opponent and double-opponent cells. These cells are integral in the opponent process of interpreting colour signals. Single-opponent neurons respond to large areas of colour. This is advantageous for recognizing large colour scenes and atmospheres. In comparison, double opponent cells respond to patterns, textures, and colour boundaries.
