Target color mismatch penalty: A target color can be set in the token memory for each digestion process, but it is ignored in the default settings. If this parameter is set greater than 0, the cell can extract less energy from another cell if it does not match the specified color. If this value is above 1, the cell actually loses energy during the digestion process if there is a color mismatch. This parameter can be used to exert selection pressure on the population, favoring those individuals that find and digest the particles with the matching color. At the same time, other populations can protect themselves from attacks by exhibiting a different color. This allows, for example, several populations with different colors to coexist peacefully.
