      @@mohamadelhajjyounes7841 (a) If the colour of the liquid above the fine aggregate is lighter than the reference colour, the amount
      of organic impurities present in the fine aggregate under test is probably not significant and the
      sample is reported as "Pass" on the test report.
      (b) If the colour of the liquid above the fine aggregate is darker than the reference colour, the sample
      is reported "Fails" on the test report and desirability of performing further tests to assess the effect
      of organic impurities on the concrete-making properties of the fine aggregate under test should be
      considered.

      Liquid Color 1, 2, or 3 (which is of the same color or lighter than the standard color of 3) means that it is acceptable to use. A liquid color of 4 or 5 would indicate that further testing is advised.
