This article presents the Color-Material-Finish (CMF) project developed for the renovation of Fortezza da Basso in Florence, Italy. Fortezza da Basso—a large, fortified complex consisting of old and new buildings—is the main venue in Tuscany for international exhibitions and cultural activities. In 2010, the Municipality of Florence started its restoration, which is still ongoing. The goal is to renovate the Renaissance parts of the fortress and replace the 20th-century pavilions with environmentally sustainable buildings, harmonically integrated in the context. The renovation started with a project aimed at assessing the preservation status of the fortress. In 2016, the Municipality of Florence developed a body of design rules, the “Fortezza System,” dedicated to the design of new buildings within the fortress. A key role was assigned to CMF design: at first, to identify the fortress CMF identity; then, to develop CMF prescriptions to harmonically integrate the new constructions with the historic parts. The CMF approach required for such an ambitious plan also had to be flexible and with wide design margins to allow architects experiment innovative CMF languages. Such conflicting needs were met by designing a CMF approach based on Chromatic Areas, that is, usable continuous areas in the color space rather than on color charts based on lists of allowed historical colors. The article shows how the developed CMF approach can contribute to the full preservation of the Fortezza historical identity and at the same time increase the autonomy of architects in their material and color choices.

Facial brightness perception is affected by skin color. It was reported that reddish skin was matched with a higher lightness scale stimulus than yellowish skin among Japanese observers. However, this trend is inconsistent among Thai, Korean, Chinese, and European observers, implying the influence factors, such as ethnicity, environment, and judgment criteria. In this study, we investigated the influence of the experimental method on facial brightness perception using test stimulus images with constant lightness and different hue angles. We examined two instructions (“Appearance match” vs. “Brightness match”) and the scale stimulus for matching (a uniform color patch vs. a face image). We further conducted an impression evaluation experiment of the whole face. The matching results from the Japanese showed a similar trend in both instructions and scale stimuli under most conditions, suggesting that matched brightness is not influenced by instruction and the complexity of scale stimuli. The impression evaluation results were similar for Thai, Japanese, and Chinese observers, with reddish faces being evaluated with higher scores in brightness. Our findings suggest the influence of experimental methods on facial brightness judgment. The holistic judgment of facial brightness would be universal among different East Asian groups, at least for the range of variation in skin color we used.

Owing to the need for beauty in modern society, cosmetics are essential to enhance femininity and attractiveness. Lipstick is effective in reinforcing femininity and increasing beauty. This study conducted a psychophysical experiment to investigate the association between lipstick colors and the impressions they create. Thirty-five observers were invited to participate in the experiment. They were asked to assess 20 lipstick colors on 23 impression scales. The results showed that the impressions created by the lipstick colors comprised three factors: charm, cuteness, and contemporary. Charm was correlated with a* and lightness value of lipstick color and the color difference between lipstick-skin colors. Cuteness was negatively correlated with the hue angle of the lipstick colors and lightness differences between lipstick-skin colors. Contemporary was correlated with chroma differences and negatively correlated with b* of lipstick color. These lipstick colors can be classified into three groups based on impression factors. The results showed that a* value of lipstick color and the color difference (
