This work aims to reproduce and characterize the traditional red color by investigating old documents. Various traditional red color which has been used in traditional costumes was investigated. So-Hong, Mok-Hong, Dae-Hong, Ban-Hong, and Chun-Hong were chosen and their spectral properties, dyeing properties and color properties were compared. Mordants and auxiliaries changed the hue, lightness, chromaticity and color strength of the dyed fabrics with natural red dyes. However, the influence of dyeing temperature and time on the dyeing properties was relatively small. The redness value ($+a^*$) of the natural dyeings was in order of Dae-Hong, Mok-Hong, So-Hong, Chun-Hong and Ban-Hong. The color gamut of Dae-Hong and Chun-Hong was limited to the small color coordinate area while that of Ban-Hong was distributed widely over the color coordinates.
