Interesting...if you see my comment/path above, I was able to do "Visible spectrum → Rainbow Chromaticity (places)."

Under the hood, the prompts are all something like this "Generate nouns that are broader, more general categories that encompass 'Piano'. Return exactly three distinct Wikipedia-style article titles that are nouns, formatted as a comma-separated list with no extra text. Do not include descriptions or adjectives. Focus on specific, named entities or concrete noun concepts only."

The outputs are then deduped from previous generations and any new options are displayed. Based on my result, if you spammed 'deeper' enough, the model would eventually have given you 'Rainbow Chromaticity'.

Uncooperative and non-deterministic.
