The numbers in the column to the right of each chart refer to the number of bits in the field being tested, and the numbers in the row at the bottom give the position of the most significant bit of each field. Green indicates that the results were "consistent" with the premise that random() produces a sequence of independent, uniformly distributed random numbers. Yellow and light blue results are marginal. Dark blue means that the generator NEVER FAILED the test (out of 1000 tries), whereas it should fail 5% of the time, on average. Orange and especially pink results are clearly unacceptable, while red means that the generator NEVER PASSED the test.
