This work aims to reproduce and characterize the traditional red color by investigating old documents. Various traditional red colors which have been used for traditional costumes were investigated. So-Hong, Mok-Hong, DaeHong, Ban-Hong, and Chun-Hong were chosen and their color properties by repeated dyeing were compared. The amount of natural dyes and the number of dyeing times improved the chromaticity and color strength of dyed fabrics. The redness value ($+a^*$) of the natural dyeings was in order of Dae-hong, So-hong, Mok-hong, Chun-hong and Banhong. The color gamut of Dae-hong and Chun-hong was limited to the small color coordinate area while that of Banhong was distributed widely over the color coordinates.
