Florida HOAs Should Regularly Review Architectural Review Board Guidelines

Question: I live in a homeowners association and serve as chairman of the architectural review board (ARB). An owner recently submitted an application to repaint the exterior of his home a bright yellow color. The home is currently painted light brown. Our ARB rejected the application because we feel that the proposed bright color is aesthetically unpleasing and no other homes in our community are painted this color. The owner is protesting the ARB’s decision and threatening to sue. The owner alleges that the ARB is breaking the law by rejecting his color request because the association doesn’t have a specific list of permitted colors. Is the owner correct? Do we have to allow the owner to paint the exterior of their home bright yellow?
