Abstract

This study presents an application of the ‘method of limits’ psychophysical technique to identify the digital colour which corresponded most closely to the colour of a real object. A chromatic scale composed of a series of digital hues was first developed to measure colour sensation. The hues were systematically presented to the participants, who were tasked with matching them to the colour of a real car model. The study was conducted under two different illuminations (white/warm light) and against two types of background contrasts (white/black) to investigate their effects on colour perception. Post-experimental analyses revealed that background contrast is a significant factor but not illumination. The results were validated at the Jaguar Land Rover Virtual Reality (VR) suite. Going forward, the methodology developed in this study could be used to examine other factors such as depth perception and viewing angles.
