Abstract
The types and concentrations of multiple anodic electrochromic compounds are selected in such a manner that RGis 1.37 or less, in which RGis a maximum value among ratios between RGB signal ratios in the transmission state of an electrochromic device and in colored states of the anodic electrochromic compounds, the RGB signal ratios are obtained from T(λ) and the sensitivity of a photodetector, and T(λ) is a normalized variable transmittance obtained by a combination of absorptions of the anodic electrochromic compounds.
