[silisili]

All adjectives precede nouns in English. Brown the university is still an adjective in this sense.

There's really nothing to A/B test here. We, especially the media, don't refer to people as Brown the color.

[perilunar]

'Attorneys General' and 'Majors General' would indicate otherwise.

Also: president elect, poet laureate, devil incarnate, court martial, etc.

[silisili]

Fair examples. Every rule does have exceptions. But none that would make Brown in the title make one think it was a skin color because of English rules.
