We are aware of the rule. We are also aware of the bit that says 'Committees will be given the discretion to mark all penalty areas as red so that lateral relief will always be allowed.' This initiative from our head groundsman came about chiefly from an R&A Juniors comp we held recently in the Faldo series. The referees wanted all of the penalty areas red to avoid confusion. Searching online, I see that many golf courses have taken this option, under R&A guidance. I was only wondering if any others on here have undergone similar changes.
We have two holes where ditches run at right angles across the fairway so were previously yellow. All other water hazards were red. We decided not to incur the bother changing the yellows until the next time the posts were to be painted as the additional relief option could never be utilised. All our PAs will be red for next season.
