Layer: An area of headspace or inner workings that separates headmates from each other. May be experienced as if they're on "different planes" of headspace, or something closer to containers for certain headmates. Often cause communication and memory barriers as well, but these aren't always present
The colors are taken directly from its companion flag, the polyfrag one. The blue part is greyed out to represent having layers while possibly not having any subsystems
A 5 striped flag, with all the stripes vertical. The leftmost and rightmost stripes are dull blue, with the large center stripe being pink. Between them are thin white stripes (or transparency, for the transparent version)
