The rainbow sent by King Triton at the end of The Little Mermaid is inverted (blue is at the top).
Has this ever been explained by someone linked to the film's creators? Possibilities I can think of include
- mistake (unlikely given how obvious it is, the budget, the professionalism, etc).
- an allusion to the "reflected" nature of the undersea kingdom (their up is our down, etc)
- a deliberate distancing of the world of the entire film from our own
- an unwillingness to upset the Gen9:13 crowd by suggesting a classical god might have comparable ability or otherwise distinguishing the two events
But I'm not really interested in speculation, just creator-attested reasons, if any exist.
