In Spectrobes, upon obtaining the Rho Cube, Aldous will add color awakening to the awakening system. When awakening a fossil, depending on the pitch of the voice the Spectrobe awakened will have one of three colors, being either its standard color or one of two custom colors; the pitch can be identified by the number of bars lit up during the awakening process. This can be done by default in Spectrobes: Beyond the Portals.
Chroma minerals can also be used to change a Spectrobe's colors. A Chroma 1 mineral gives a Spectrobe its standard colors, Chroma 2 gives it its Custom Color 1, and Chroma 3 gives it its Custom Color 2.
