Color Space Object (634nm), 2019/2024

The color space objects "634nm" and "452nm" each consist of a body made of coated gypsum fiberboard and a lacquered MDF board respectively. Inside there is a concave curved HDF panel and two side panels painted in monochrome with pigments in matt dispersion.

This work was inspired by James Turrell's light installations. In contrast to his architectural approach, however, this work attempts to implement a color field as a minimalist wall object. One of the main challenges was to illuminate a hollow space as evenly and indirectly as possible while keeping the depth of the image to a minimum. The formal design is also based on this objective (e.g. the maximum height of the opening, the lateral fade-outs or the concave curvature of the painted surface).

In order to achieve the most intense color effect possible, high-quality pigments and LEDs with excellent color rendering values were used. As a result, this work offers the possibility of perceiving a color field with wavelengths of the color spectrum that cannot be displayed even with the best monitors.

The measurement using a color spectrometer revealed a color spectrum in the range 610nm to 680nm and a peak wavelength of 634nm. The measured color spectrum is therefore clearly outside the color space coverage of monitors (the wavelength of primary red is 612nm in the AdobeRGB color space and 615nm in the DCI-P3 color space.
