Disney created a color called Go Away Green. A very bland green shade you see a lot of in the park but don’t really think anything about. It was created with the idea that the common eye would glaze right over it. Truth is, unless you’re looking for it, it is all too easy to just glance right past anything painted in this all-too-neutral color. No See-Um Green is actually in a lot of places. The fences, buildings, the wall around the park… And most famously, the door to the exclusive Club 33.
