In a condominium or HOA the authority of the governing board is typically limited to the EXTERIOR of a unit or a house, and they can only address interior issues if they affect other residents (noise, odors, etc.). I’ve never heard of an HOA restricting paint colors INSIDE a home, but I’m sure co-op boards do it all the time.
Many HOAs require white curtains or blinds and drapes with a white lining.
