   When you apply the ink (or paint) as a layer on the paper, then the light   
   has to reflect off that ink before it gets to the paper. This is similar   
   to how a blackboard works, which is how you can write light-coloured text   
   on a dark blackboard.   
      
   Subtractive mixing requires actually mixing the paints.
