Spectralism

Spectralism is a religious movement from the IDW portion of the Generation 1 continuity family.

Spectralism is a Cybertronian religious movement, placing great importance on colors, and their meaning. For example, blue and purple are considered both a sign of grief and a statement of intent. They also have a greeting identified as the "Call of the Wavelength". Spectralist funerial customs involve making a coffin from material found at the scene of the deceased's death.
