chalkaspis officer color choices?

[Giannis K. Hoplite]

Yes there are freskoes showing red helmets but the red or amaranth colors are asociated with horsemen although this can be very subjective.

Stefane,the fresco with the red-black helmet has also a hoplite or pelte shield between the two helmets and swords.Also the Sidon sarcophagus has a painted red helmet that most probably belonged to the unhelmeted foot soldier nearby.
Ruben,I don't remember blue helmets in a greve stone.Perhaps Stefanos could post a photo?
