“…While inkjet printing systems follow RGB logic and allow for color mixing, the Farbglas color palette does not entirely follow the additive logic of traditional color models. 19 The mixing logic of this product will be part of future investigations, and this paper focuses on an approach of dispensing colors from channels separately. By controlling the motor rotation, vertical screws start rotating to transport and dose the granules (Figure 4).…”

This research investigates a new digital fabrication method for large-scale polychromatic glass elements. Glass elements with locally differentiated properties usually require manual labor or are limited to film applications of secondary materials that are incapable of producing material texture and relief in glass. To create mono-material glass elements for buildings with customized color, opacity, and relief present in the same glass element, this research investigates a novel robotic multi-channel printing process for industrial float glass. Mono-material polychromatic glasses do not require any additional material and can be fully recycled. This paper presents a design-to-production workflow for the construction scale within feasible cost. Investigations include kilning and material considerations, multi-channel tool and fabrication setup, tool path generation, process parameter calibration, and large-scale prototyping. The co-occurrence of locally varying opacities, colors, material textures, and relief within one glass element enabled by the presented robotic fabrication method could allow for novel optical and decorative features in facades and windows.

“…The ones that do not, have some coordinate only marginally different (0.01 range, see later) from 0 or 1. From a formal perspective, the rgb cube is the natural arena for the object colors (Küppers, 1978, 1989, 2005; Smith & Lyons, 1996).…”

How many colors are there? Quoted numbers range from ten million to a dozen. Are colors object properties? Opinions range all the way from of course they are to no, colors are just mental paint. These questions are ill-posed. We submit that the way to tackle such questions is to adopt a biological approach, based on the evolutionary past of hominins. Hunter-gatherers in tundra or savannah environments have various, mutually distinct uses for color. Color differences aid in segmenting the visual field, whereas color qualia aid in recognizing objects. Classical psychophysics targets the former, but mostly ignores the latter, whereas experimental phenomenology, for instance in color naming, is relevant for recognition. Ecological factors, not anatomical/physiological ones, limit the validity of qualia as distinguishing signs. Spectral databases for varieties of daylight and object reflectance factors allow one to model this. The two questions are really one. A valid question that may replace both is how many distinguishing signs does color vision offer in the hominin Umwelt? The answer turns out to be about a thousand. The reason is that colors are formally not object properties but pragmatically are useful distinguishing signs.
