Virtual reality (VR) technology ofers vision researchers the opportunity to conduct immersive studies in simulated real-world
scenes. However, an accurate colour calibration of the VR head mounted display (HMD), both in terms of luminance and
chromaticity, is required to precisely control the presented stimuli. Such a calibration presents signifcant new challenges, for
example, due to the large feld of view of the HMD, or the software implementation used for scene rendering, which might
alter the colour appearance of objects. Here, we propose a framework for calibrating an HMD using an imaging colorimeter,
the I29 (Radiant Vision Systems, Redmond, WA, USA). We examine two scenarios, both with and without using a rendering
software for visualisation. In addition, we present a colour constancy experiment design for VR through a gaming engine
software, Unreal Engine 4. The colours of the objects of study are chosen according to the previously defned calibration.
Results show a high-colour constancy performance among participants, in agreement with recent studies performed on
real-world scenarios. Our studies show that our methodology allows us to control and measure the colours presented in the
HMD, efectively enabling the use of VR technology for colour vision research.
