YInMn Blue
Modern inorganic pigmentComposition and Properties of YInMn Blue
The chemical formula of the new pigment is YIn1-xMnxO3. Its color can be changed by adjusting the proportion of manganese ions Mn3+ which are responsible for the intense blue color. This pigment is one of the most recent contributions of the chemists to artists’ palette.

Preparation
The pigment can be prepared by heating the oxides of the three elements yttrium, indium, and manganese (Y2O3, In2O3, and Mn2O3) in the air to a temperature of 1200 – 1300 °C (1).
Preparation of the Pigment
History of Use
The pigment was first synthesized in 2009 at the Oregon State University and patented in 2012. It is now commercially available as an artists’ pigment.
Identification
Reflectance spectra UV-VIS and IR
Spectrum by Chemistry Dept, Oregon State University
The spectrum of YInMn blue in comparison with the spectra of two forms of cobalt blue. YInMn blue shows strong reflection in both the UV- and the IR-regions of the electromagnetic spectrum (1).
