       8 . The method of  claim 7 , wherein said method is carried out using at least one ratio of a plurality of said throughputs, said ratio is at least one of controlled and adjusted.  
   
   
       9 . The method of  claim 7 , wherein said method is carried out using a plurality of headboxes, each said headbox including at least one said partial suspension stream and a headbox throughput, at least one said partial suspension stream including a content of said filler of varying said sizes of said filler particles, at least one of said headbox throughput and said content are at least one of controlled and adjusted.  
   
   
       10 . The method of  claim 9 , wherein said method is carried out using three said headboxes to produce three primary colors through three distinct said sizes of said filler particles which results in said predetermined color of the fiber web.  
   
   
       11 . The method of  claim 1 , wherein said method is carried out producing a finished fiber web including a plurality of the fiber webs, each of the fiber webs including said fillers of varying said sizes of said filler particles, each said size of said filler particles associated with a different color, said sizes selected to produce said finished fiber web in said predetermined color, resulting from said different colors produced by said sizes of said filler particles.  
   
   
       12 . The method of  claim 1 , further including the step of producing at least one said filler particles by at least one of triggering a chemical precipitation reaction and a refining process, said producing at least one said filler particles step is prior to said including step.  
   
   
       13 . The method of  claim 1 , wherein said method is carried out with said filler including at least one of precipitator, synthetic material, calcium carbonate, talc, TiO 2 , silica and similar materials.  
   
   
       14 . The method of  claim 1 , wherein said method is carried out by loading the fiber suspension with said filler through a chemical precipitation reaction.  
   
   
       15 . The method of  claim 14 , wherein said chemical precipitation reaction produces a crystalline precipitator particles.  
   
   
       16 . The method of  claim 15 , wherein said precipitator is calcium carbonate.  
   
   
       17 . The method of  claim 16 , further including the steps of adding at least one of calcium oxide and calcium hydroxide to the fiber stock suspension, the fiber stock suspension including fibers, the fibers are loaded by said adding step; and supplying carbon dioxide to the fiber suspension thereby triggering said chemical precipitation reaction.  
   
   
       18 . The method of  claim 1 , further including a refining process step to produce a predetermined said size of said filler particles.  
   
   
       19 . The method of  claim 1 , further including the steps of loading the fiber stock suspension with said filler through a chemical reaction, the fiber stock suspension including fibers which are loaded with said filler; and refining the fibers thereby producing a predetermined said size of said filler particles.  
   
   
       20 . The method of  claim 1 , wherein said method is carried out using a chemical color as a brightner.  
   
   
       21 . A method for a production of a fiber web from a fiber stock suspension including a filler, comprising the steps of:. 
 loading at least one filler including a plurality of filler particles in the fiber stock suspension; and    refining the fiber stock suspension after said loading step to produce said plurality of filler particles in a predetermined size range.
