[The perceptive, mnemonic and semantic levels of subjective reflection].
Comparison of different colour stimuli between each other has shown that the whole quantity of colours is projected onto the surface of a sphere in a four-dimensional space. Geometric distances between the points representing colours are directly proportional to subjective differences between the colours. Information on the perceptible colours is recorded in the long-term memory. Traces of the colour memory form a mnemic space isomorphous to a perceptive colour space. Traces of the colour memory are connected by means of two-way bonds with symbol representation of colours which form a semantic colour space. Analysis of subjective differences between the colour names has shown that the terms of colours are represented by points on the surface of a hypersphere in a four-dimensional space. Colour stimuli being reflected at the perceptive, mnemic and semantic levels become an act of consciousness with participation of the activating brain systems.
