I had a saliva drug screen test done for amazon

So when I was doing it there was about 5 people there with me taking it also when I took the test out its bin 15 min mine was kind of red and others where blue I don't smoke or do any drugs of any kind only thing I did was drink a beer or two the night before the drug test . Why did mine have a diff color and will it affect the results ??

It depends on the test they were using but some saliva tests will detect alcohol from the time of the test back 12 hours.
