Closing this one. It targets the input_color domain, which no longer exists: the backend proposal was reworked as a config-entry helper under the color domain, now up for review at home-assistant/core#177605.

The more-info dialog has been rewritten against the new domain and will go up as a fresh PR once it is rebased on current dev, linked from the core PR. Nothing here needs review in the meantime.
