The first phase of the study involved a survey of the vehicle topcoat colour in two areas within a day and with different days. Subsequently, the second phase involved analysis of paint chip samples obtained from the varying parts of the same car and different cars carrying the same topcoat colour using Attenuated Total Reflectance-Fourier Infrared (ATR-FTIR) spectroscopy.

From this study, it was noted that the topcoat colour determination by witness or victim, particularly related to vehicular accidents, shall be interpreted carefully to assist the forensic investigation and interrogation.
