COLOR QUALITY MEASURES

Although IES TM-30-15 and ANSI/IES TM-30-18 are providing a much more comprehensive description of the color properties of a light source, they are not yet accepted by the CIE. I hope that designers continue to request IES TM-30 metrics and manufacturers will continue to provide those information on their products.

ACCURATE COLORS IN COMPUTER RENDERINGS

Computer renderings are indispensable means in presenting ideas and designs in the lighting industry of today. The quality of the lighting simulation provides an indication of how the suggested design looks like when realized.  For this reason, the accuracy of color in lighting simulation is critical as it needs to communicate a clear picture of the suggested lighting effect to stakeholders. To achieve accurate color representations on the display is not always easy. Decisions need to be taken on which aspects eventually to compromise. A problematic situation appears as lights are used that have a higher saturation than can be rendered on the display.
More about this problem and a strategy how to deal with it is described in the paper Considerations for planning colored lighting by Chia-Chun Liu and Markus Reisinger. The paper was presented last year in October in Venice on the conference Color and Light in Architecture.

DESIGNING A ROOM FOR LIGHTING EVALUATION

Lighting can only be evaluated together with the environment. If there is light present in a space or architectural environment, we can have a visual sensation of this scene with our eyes. Lighting thus affects how the physical scene with its objects and surfaces appears to us humans. Read more
