In this paper, we carried out an experimental research for establishing the evaluation of metal's surface texture by analysis of surface color. The materials of samples used in the experiment were aluminum alloys (A2017, A5052), stainless steel (SUS304) and copper alloy (nickel silver C7541). The surfaces of samples were burnished by use of waterproof abrasive papers. The surface roughness of samples evaluated by arithmetical mean <i>Ra</i>, root mean square slope <i>R</i>Δ<i>q</i> and mean width of the profile elements <i>RSm</i>. The experimental results showed strong correlation for three different roughness parameters. Consequently, "<i>Ra</i>" was used as roughness parameter. As <i>Ra</i> decreased, the glossiness exponentially increased. The evaluation method of surface color was applied to <i>CIELAB</i>. The lightness <i>L</i>* in <i>CIELAB</i> decreased as <i>Ra</i> decreased. Thus, it showed that relationship between <i>L</i>* and <i>Ra</i> inverse correlation between glossiness and <i>Ra</i>. Moreover, surface color of four different materials showed that the chromaticness of blue increased as <i>Ra</i> decreased.
