The purpose of this study was to manufacture colored Hanji for interior materials by combining color therapy and natural dyeing. To manufacture colored Changhoji for interior materials, seven species of dyestuff were selected as a results of preliminary natural dyeing. As mordants, 0.5% $AlK(SO_4)_2{cdot}12H_20$ and 0.5% $Cu(CH_3COO)_2{cdot}H_2O$ solution were used respectively. To estimate natural dyeing properties of Changhoji, the value of $L^*,;a^*,;b^*$ and Munsell HV/C were measured by spectrophotometer. The super eight colors produced as follows; red from safflower, orang from goldthread and gardenia, yellow from turmeric, green and turquoise from indigo and pagoda tree flower, violet and magenta from sappanwood, and blue from indigo.
