I'd leave it black but consider painting the fence black (sorry, bit of a job). You'll be very pleased with the results. The fence will 'disappear', blending in with the fence your eyes won't rest on it at all. Your pool and pot plants will be the star. If you decide on a different colour I'd still suggest you paint the fence to match.

Taubmans chilly water (more green) or misty rain (more blue). i'm sure there was a design dilemma post from a while back that gave the Aussie paint answer to this question. Hopefully someone who knows will see this and link it.

Dear Creatively Challenged , I can recommend Dulux Colour Consultants, I gave up after about 5 sample pots . At the time it cost me $150 and if I used dulux paints I could claim a full refund . That was 12 years ago . I didn’t realise at the time just how good they were , the colours are still in fashion but it’s ready for another paint job for sure. It was such a relief to have someone in who is trained and fully understands colours and fashion and what goes with what . I finally stopped stressing about it and got the job done ✅
