Vehicle Color; Multiple coatings of automotive paints are apply to vehicles for both protective and decorative purposes. These paints are frequently encounter as trace evidence in vehicular accidents, allowing for the association of question samples recover from a scene with control samples of known sources through forensic examination.
In certain vehicular accidents such as hit-and-run; the investigative team would look for the plate number and color information allege by a witness or victim of the accident in order to begin their investigation. Unfortunately, in cases where witnesses either did not notice or cannot remember plate numbers; so the colors of vehicles, the descriptions of which are base solely on the perceptions of witnesses, become the main lead. Therefore, the inability to correctly describe the colors of vehicles may lead investigations astray.
Compilations of vehicle color
During a trial, investigative officers or forensic scientists are often require to explain the evidential value of question paint evidence recover from a vehicular accident, including its color. Surveys and compilations of vehicle color distributions generalize as topcoat color (technically, unlike the solid paint system; so the top layer of a metallic paint system is a colorless clear coat that covers the metallic basecoat) have conduct to assess the probative value of a vehicle’s color in supporting forensic conclusions.
In addition, color determination through careful interpretation of submit paint samples; so can also be correlate with the color momentarily perceive by a witness during an accident, although this is often difficult. Any lack of accuracy in describing the color perceive by a witness; also especially so if there are two or more witnesses, would impact credibility during cross-examination.
In general, the frequency of matches in topcoat color determination; so both for stationary and moving vehicles, could be relate to their relative on-the-road distribution. This study indicate that using basic colors without shade variations could lead to better determination of color by an observer; so resulting in a greater frequency of matches. The motion of vehicles did not have much effect on the scoring a match, given that the environmental conditions were adequate for an observer to encode the color.
Forensic intelligence purposes
This study supports that for forensic intelligence purposes; so cases involving descriptions of vehicle topcoat colors shall need greater investigative efforts; so including a more careful interpretation of witness testimony. It should also be emphasize that individual differences could lead to differences in color perception; hence especially when involving intermediate colors.
A survey to investigate the inter-rater reliability of color determination; so among observers who visually perceive the topcoat colors of both stationary and moving vehicles indicate that the frequencies of matches; also subsequently inter-rater reliability of color determination among observers; so significantly increase when using basic color descriptions, disregarding their shades.
White and black had the greatest matches; ao while intermediate colors like green-blue, yellow-green, red-orange, gold-bronze, and red-brown were consider confusing; also thus require careful interpretation during forensic investigation. Information from this study can prove useful in interpreting witness; also descriptions of vehicle topcoat colors for more reliable statements.
