Colour revolution affairs that destabilize economy, conflict with the law and represent a new form of warfare. President Vladimir Putin said that Russia must prevent colour revolutions: "We see what tragic consequences the wave of so-called colour revolutions led to. For us this is a lesson and a warning.

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.
