Rational Painting has closed. Thanks to everyone for participating over the years.
We kept it running long past its intended lifespan, but it was always a volunteer effort run by its creators, and it reached the point where the cost and labor to keep it going far outweighed its usage. The world has largely moved on from private forums and migrated to social media, and it's time to recognize that. Rather than attempt to make RP into a self-sustaining commercial project involving advertising or member fees, we have decided to retire it gracefully.
We're all still out there if you want to reach out to chat about Munsell or painting.
