In this cartoon–
A character refers to Planet Vivid.
Since it seems to connect to scantily-clad women, is it a nudy bar? A lingere store? Something else?
What is Planet Vivid? 
BTW–the cartoonist has connections to Philadelphia, if that helps. Philly slang?
Vivid is the name of a porn company.
FWIW,

Ummmm…I’m not certain that’s it.
No mention of Planet Vivid.
Still…
Dude, that’s it. That’s the joke. That if there were a planet populated by porn stars such as the ones that work at Vivid (one of the most well-known porn studios), that’s what someone working an ordinary, blue collar job would look like.
You’re not the same guy that asked if “flacid” was another word for ice cream headache, are you?
Yes, that’s it.
Given your posting history, I surmise that you are simply oblivious to the joke in the comic, so I will attempt to explain it in more explicit ( 
) terms.
There is a famous pornography company called Vivid. Any casual porn viewer or connoisseur will have heard of them.
The woman in the comic strip is wearing a sexy leather outfit.
Said outfit is out-of-context in an everyday situation. The juxtaposition of strange things with mundane things is often a source of humor in human culture.
Attempting to explain the juxtaposition, the character posits that the woman is from an entire planet named after the world’s most famous pornography company. Imagining a planet of such people is both additionally humorous and titillating. (If you’re twelve.)
But how does the artist know whether Planet Vivid is even capable of sustaining life?
If it can sustain an erection, I’m pretty sure it can sustain life.
You should email Brad (the author of the strip). He will most likely respond back. I have met him at conventions and he was a pretty laid back guy. Most web comic artists will respond to fans emails unless they get tons and tons of email.
I was thinking that Planet Vivid was something like Planet Hollywood–a club/restaurant.
Interesting concept. Maybe you should pitch it to Vivid Video:
“Planet Vivid” - for when you really feel like eating out!"
Well, it’s not.
Humor. It is a…difficult concept. Your species is a very interesting one.
But it should be!
Hell, I’d try it. I’d make Hooters look like a bunch of prudes, too.
I want to move to planet Vivid!
Its main culinary competitor is the Y.
Well, i*[Planet * is a fairly common expression. I’ve heard it a lot of times. It means “the reality inside your head”
Examples : “planet Chomsky,” which means the reality as perceived by Chomsky’s.
Planet Obama which means the reality as perceived by Obama.
And in the same idiom, Planet Vivid means reality as seen in Vivid movies.
Yes, but what about the atmosphere?
And would it cure my sexlexia?
