Veterinarians don't seem to have any color code, that I know of. Many don't use crosses (they tend to have cutsey animals).
The hospital near where I live has a blue cross at its emergency entrance, and a nearby urgent care clinic also has a blue cross, however, another nearby urgent care facility has a red cross.
I don't know of any pharmacies that have any prominent cross displays. They tend to have their own branding (which may or may not have a cross integrated).
Interesting, as here (France and Belgium) only pharmacies consistently display a green cross. All of them do, and I wouldn't be surprised if that was a legal requirement. It's not as consistent for the other medical facilities, but I'm pretty sure that at the minimum they never use the "wrong" colour.
I don't know where this usage comes from (and can't really look it up now) but now that I think of it "the Red Cross" is a doctors organisation, so it fits the scheme I told about.
