Abstract
Windowpane with optical multilayer coatings has ability to control the color and solar energy through the glass. The optical transmittance in the visible region is affected by the interference in the multi-layer coatings. It follows that any color emerges on the scenery through the window. Therefore, it is important to design the color according to the user's own preferences for residential usage. The chromaticity diagram can indicate a specific color by using RGB values in the two-dimensional diagram. This paper reports on the results of design of the multilayer coatings to satisfy the user's sense of the color using the uniform chromaticity scale diagram.
