The stimuli experienced were like those found in architectural contexts – large painted surfaces with brush texture and small irregularities that cause shadowing. We observed and recorded participants ’ locomotion, gestures, expressions, and behaviors with the intent of finding both commonalities that might exist and the range of responses that would occur. We believe that design practitioners will find both the commonalities and differences interesting.

The study had to do with metamers produced through a range of lighting technologies – colors that appear similar but are composed of different spectra produced by the technological substrates of the lighting systems compared within the experimental conditions. This resulted in similar but not identical colors. In tightly controlled experimental work, these stimuli would not be considered to be the same. But in this case, the investigation has to do with the color generating ability of the technologies. The fact that, in some cases, the match could not be exact was part of the question as we had formulated it. As an exercise that might inform practice , we retained the pragmatic conditions found in practice for our experimental conditions. We expect that this may not have been acceptable under a different paradigm because the question would have been formulated in a different way. We are also interested in the knowledge that might be obtained through a different ways of framing the question, however, in this study we did pursue that knowledge .

While the subject of this chapter is not the work of the dissertation itself [3], several of its findings are reviewed here in order to illustrate the kinds of observations made using these designerly methods.

It was found that informants could not detect a difference between colored light projected on a white surface and white light on a colored surface when seen from a distance. But those who immersed themselves in the luminous conditions, by walking into the semi-cylindrical spaces could easily tell them apart. This is because the ability to make the distinction does not depend on the luminous surface alone, but also on the way the projected color reacted to another surface, one that was inevitably brought with the perceiver. In this experiment, it was, for example, the pad of white paper used to take notes, or a shirtsleeve, or the hand of the informant that could register the difference between the illumination sources beyond the experimental surface in question. Our use of the ‘black box’ effectively allowed for the simultaneous conduct of two studies, one distal, approximating a laboratory study investigating color perception under controlled conditions, from an information theoretic perspective, and the other a less controlled ‘field’ study, approximating an embodied architectural field condition. In the first study we found that the percepts are indistinguishable in observation. In the second study we found that the conditions were perceived as distinct when the informant moved from one condition to the other. Not all of them did.

The informants were remarkably different in their reactions to colors and in their use of the space – in how they interrogate colors with respect to movement.
