In most computer graphics today, the goal is to make visualizations that “look good and natural” rather than to make correct simulations of reality1,2. However, when using Virtual Reality (VR) as a colour design tool, light and colour must appear in the VR-environment as in reality. In this project, the aim is to simulate perceptual light and colour phenomena more correctly. Real rooms are compared to digital models. In the digital models, some contrast phenomena did not appear. The poster presents a work in progress, were we elaborate on rendering solutions. The first step was to filter digital renderings with the Automatic Color Equalization (ACE) algorithm. By filtering rendered textures of each multicoloured wall, the virtual reality model improved in colour appearance. However, further adjustments of ACE are needed in order to include 3D colour phenomena.

Nyckelord: colour, colour appearance, Virtual Reality, Virtual Environment, space, spatial experience
