Purpose: This study was conducted to investigate the colors of zirconia and veneered ceramics according to the build-up method of veneer porcelain. Methods: The samples were divided into three groups: a group for which a liner was applied to the zirconia surface and dentine coating was built up and burned (Cz1), a group for which the dentine coating was directly built up and burned (Cz2), and a group for which the samples were wash-burned with dentine coating and a dentine coating was built up and burned again (Cz3). The the colors were measured with a Spectrophoto-meter. Results: The average $L^*$ value of the Cz3 group was the highest among the groups at $59.1{pm}0.5$ (P<0.05), followed by Cz2 at $57.5{pm}0.8$ and Cz1 at $56.6{pm}1.3$. The $a^*$ value of Cz3 was negative at $-0.0{pm}0.0$ and the $a^*$ values of Cz2 and Cz1 were positive at $0.2{pm}0.1$ and $0.4{pm}0.0$, respectively (P<0.05). The $b^*$ of Cz1 was the highest at $11.2{pm}0.6$, followed by Cz3 at $10.8{pm}0.5$ and Cz2 at $10.5{pm}0.8$ (P<0.05). Conclusion: Compared to other experimental groups, the Cz3 groups showed the brightest colors with high brightness and relatively low green and yellow levels.
