Rainbow Sign made use of their space in every way possible. The program hall was where concerts, art shows and literary events took place, as well as large parties and dances. The restaurant served in both the program hall and the clubroom, and could accomodate up to 215 people for a sit-down dinner. Front of house manager Charles Brown and his staff of seven were always moving things around to make Rainbow Sign’s multifunctionality possible.

Down the hall was the office shared by Brown and Mary Ann Pollar, followed by a large conference rooms that could seat twenty-five people, an activity room with games and a billiard table, and the clubroom which had a full bar, couches, and a door which let out to a small courtyard. The multi-purpose rooms could each seat fifteen to twenty people. All kinds of organizations rented these spaces, from American Indian groups to Chicano groups to the Links debutantes. Within the shared space of the Rainbow Sign existed a shared peace and mutual respect fostered in part, no doubt, by the coalition-building experience of Charles Brown and the egalitarian vibration of Mary Ann Pollar.
