Did you get a salinity yet? The salt test is one of the most definitive color transitions of all the drop tests. but like all drop tests if you use too much reagent (~50 drops) it will create a testing error that makes the results un reliable. So if you get to 30 drops just stop and do a diluted test or use a smaller sample. The actual endpoint is a salmon brick color.. but if it pops to brown you've overshot it with one drop! Are you using a stirrer?
