   RESORSA — Visual System v1.1
   A black workspace illuminated by information. The environment is
   black; charcoal/graphite carries surfaces; white carries the R_
   brandmark and type; blue/teal/green are action; lavender/pink/peach
   are restrained supporting state; the full palette only lights the
   edges. Colour illuminates the black — it never replaces it.
