Novel Ca6Ba(P1-xMnx)4O17 sky-blue pigments are synthesized by a conventional solid state reaction method. These pigments exhibit a strong optical absorption in the yellow-red light region. LaAl0.90Mn0.10Ge2O7 showed the most vivid sky-blue hue. Ca6B(P0.99Mn0.01)4O17 has CIE color parameters of L* = 75.47, a* = −11.67, b* = −10.29, C = 15.6, and H° = 221.4°. This pigment has a high thermal stability of color and also has excellent light resistance to the UV irradiation.
