I was always told that to change the colours of common property would require the input of owners voting on the change. The old 75% for not more than 25% against rule.
It would concern me if EC’s could just pick colours for common property. I question their decision making as is, without having to put colour choices in the mix.
When I was on the committee I had wanted to get permission to repaint with different colours, mainly using less colours, not necessarily changing to a different scheme. So when I was told it would need 75% approval, and knowing how indifferent the owners are here about getting involved or having any input except complaints, I decided to drop it. Had I known I could just change it I would have gone ahead. Would have not only improved the look of the complex but probably been less for repainting in the future with less colours needed each time.
