There are more substances than colors, so to increase analysis precision use a kit with multiple reagents. Exact color of a reaction depends on adulteration, quantity, lighting, temperature, exposure to air, storage, as well as reagent quality and degradation. Positive or negative result does not indicate if a substance is safe. No substance is 100% safe.
