To improve the color of deposition, various agents were added to brass baths of 0.13 A/dm2 of current density and 58°C of temperature
The change of color of the deposition was observed by drawing the distribution of spectrums of the luminous reflectance by Beckman spectro photomater, in order to show the change according to the JES standard. (1) In the spectro charcteristic curve, the minimum point moves to the side of short wave length with the increase of yellow color, and the blighter the yellow color, the more evidently appears the minimun point. (2) In the chromaticity diagram, the best color deposit exists in the middle of the dominant wanelength between 570 and 580mμ, the purity being 30%, and the luminosity within the limits between 27 and 33.
