Given the ever-growing body of evidence on the importance of daylight in synchronizing circadian rhythms, the issue of appropriate indoor daylighting is becoming increasingly important. Among other factors, the density of the built environment and the façade colors can determine the non-image forming (NIF) potential of daylight. The presented study is a reanalysis of data on the influence of façade color and urban canyon configuration on the spectral properties of daylight irradiance received on the opposing façade. The NIF potential was evaluated by Equivalent Melanopic Illuminance and the Relative Melanopic Efficacy coefficient, which were linked to Sky View Factor (SVF) variance through linear regression. The results show a high impact of façade color on the NIF potential of daylight at SVFs below 0.35, suggesting that considering facade colors during urban planning stages is crucial for maximizing daylight exposure in high-density areas. Furthermore, SVF was proven to be an appropriate geometric indicator for evaluating the daylight potential at the urban scale.
