"color" facet on /search returns zero results for known and valid values

Describe the bug

The color facet documented at /search does not appear to filter correctly. Querying with a project's own color value (taken directly from that project's /project/{id} response) returns zero hits, even though the project exists and is indexed under other facets (query alone finds it). Testing a numeric range around the known value also returns zero hits, which suggests the field may not be marked as a filterable attribute in the search index, rather than a mismatch.

Steps to reproduce

1. GET /project/sodium and note the color field (8703084 at time of writing). Also note that the project is indexed and searchable.
2. GET /search?facets=[["color:8703084"]], returns hits: [], total_hits: 0
3. GET /search?facets=[["color>=8700000"],["color<=8710000"]], returns hits: [], total_hits: 0

Expected behavior

Searching with the "color" facet set to a project's actual indexed color value should return that project among the hits, consistent with how categories, versions, and other documented facets behave.

Additional context

Tested on multiple project colors to no avail.

I'd like to clarify that this is certainly NOT a priority over the other issues. I heavily doubt anyone is actually searching by color, however it is still a bug so I shall report :)

i think it's more likely we just remove that from the documentation, why tf would anyone be filtering by the color decimal value lol
