The first design: the yellow emphasis comes from the fact that yellow is often associated with lunacy (ex: “The Yellow Wallpaper” by Charlotte Perkins Gilman). Range of yellows represents diversity in lunacy. The angled Psi represents both alternative ways of perceiving the world, and alternative views on mental health.
So you probably can see the direction this is taking. Right now we’re in the idea phase, bouncing concepts around. If you like any of these flags, or would change something, please message me at: splitminds(a)gmail(dot)com – send your own designs as well, if you like!
