All colour changes start after a few seconds, if the corresponding bases are present they last a little longer. In all cases, the colour is fully developed after a maximum of 1 minute. As time progresses, there is only a slight deepening of the colour. The resulting colouration is stable for several hours:
In the presence of cocaine in the sample under investigation, a colour change from white to pale pink to turquoise to light blue occurs.
In the presence of the base (crack) in the sample to be tested, the colour change takes somewhat longer.
