Spock's blood is as green as any other Vulcan's, and apparently it's mostly Vulcan in chemistry, since Sarek was able to receive a transfusion from Spock (albeit with some "human elements" filtered out). Since iron-based and copper-based blood chemistry are incompatible, it wouldn't make sense for his blood to be a blend of both. (Indeed, it's implausible that Amanda could even have carried him, since mother and fetus share blood. Perhaps he was artificially gestated, although there have been attempts in tie-ins to handwave some kind of biological workaround for that.)
However, it may have been the original intention for full Vulcans to be greener, or more alien. Note that in "Mudd's Women," Harry could tell Spock was "part-Vulcanian" just by looking at him, which implies that he looked more human than a full "Vulcanian" would. (Which would fit with Spock's line in "The Corbomite Maneuver" about the Scary Balok Puppet looking like his father.) But then "Balance of Terror" required the Romulans to look like Spock so he could be suspected of being a spy, so that idea was evidently dropped or forgotten.
He was goldish, not green. That was the intention.

Yes, Leonard Nimoy's Spock makeup was more yellowish than green. His skin color never looked really green to me on TV.He was greenish-gold, in fact. Here's an item on the makeup color that was custom-designed for Nimoy to wear as Spock, "LN-1" (which has been used for Vulcans ever since).

As a side note, the in-universe rationale for Vulcans having green blood is that their hemoglobin (or Vulcan equivalent) is based on copper rather than iron. In fact, many species of mollusks and arthropods have a protein called hemocyanin in their blood, which uses copper as its oxygen-binding element. However, it's an inefficient carrier of oxygen and would never work in a warm-blooded vertebrate.
But whatever color he was I still think pure blooded Vulcans should have looked different than Spock given the fact that he was a Vulcan-Human hybrid.
Of course, there's no guarantee that a hybrid will end up looking "in between." Some children of a mixed-ethnicity couple can look more like their father while others look more like their mother. I've even heard of one or two cases of fraternal twins where one looks black and the other looks white. Spock looks fully Vulcan, but it's possible that some other human-Vulcan hybrid might look almost entirely human.
I don't recall any mention in Trek TOS of Vulcans thinking that humans have a particular smell. Is that from one of the later Trek incarnations?. . . Remember how Vulcans feel about the smell of humans?
Vulcan physiology will have evolved to conserve water as much as possible in the hot, dry environment of their native planet. So Vulcans probably don't sweat much, if at all. Maybe they cool their body temperature by panting like dogs.This regardless of whether full Vulcans have a distinct smell of their own (which their own noses are more or less incapable of detecting), or have virtually no perspiration and therefore much less in the way of body odor.
