Why is Jester blue and Lillith white in Critical Role?

Question

I do not watch Critical Role and know very little about it.

However, whilst looking into different skin colours for tieflings, I discovered the characters Jester Lavorre, who has blue skin, and Lillith Daturai, who has white skin. I am curious to know what in-universe lore exists in Matt Mercer's homebrew universe to explain why these tiefling characters have the skin colour that they do. Searching online, I have been unable to find such information, simply that they are the colours that they are, not why.

I believe the Explorer's Guide to Wildemount book is out now, and I don't know if this is the sort of thing that would be in that book, but I don't know where else such lore might be found besides watching the show (or possibly statements by those involved in the show, such as Matt Mercer, etc). For reasons unrelated to this question/lore that I don't want to expand on, watching the show is not something I plan to do, but I'm still curious about the universe and the lore relating to these tieflings' skin colour.

So, from an in-universe lore perspective, why is Jester blue and Lillith white in the Critical Role homebrew universe?

Answer 1

Jester's coloration is explained in the narrative.

Critical Role Spoilers: Although Jester's mom is a (red-skinned) tiefling, her father is a

water genasi.

This lends her the blue color, as well as the decidedly non-tiefling resistance to cold damage, instead of fire damage.

Lillith is a bit less clear

No mention (to my knowledge) is made of Lillith's coloration. It is possible that she is simply extremely pale, or has albinism. The 5e player's handbook says that Tiefling coloration can be anything a human could have. Very pale or albino coloration is not out of the question.

As an aside, the world of Exandria, Matt Mercer's world, is quite a bit more varied, and less likely to be concerned about the lore or rules in many ways. The goal of the stream/podcast is to tell a good story, and if a blue or white tiefling is part of a good story, then it'll get in there. Similarly, Matt is often willing to bend the rules to allow something interesting or to add inclusivity to the world (see the blind shakaste, for example, who sees through a hummingbird familiar).

Answer 2

Re: Lillith...

Hi folks! Kit here - Lillith's player. Super simple explanation for Lillith's white colouration: it's due to albinism. She's an albino tiefling :) Hope that clears it up!

Answer 3

Jester was blue because....

Her father, The Gentleman, is a water genasi.

The above relationship is well known, but as the cause for Jester's coloration and resistance to cold damage, Jester concludes that it is the reason for her color in episode 34, "Encroaching Waters":

LAURA: (gasps) My dad is from islands! At least he was. Did you know my dad might be The Gentleman?
ASHLEY: You mean–?
TRAVIS: Yeah, that happened.
SAM: The moist guy.
ASHLEY: The guy that sweats all the time?
TRAVIS: Has all our blood.
LAURA: (whispering) That’s why I’m blue!
ASHLEY: Jester!
LAURA: I know!
LIAM: It’s probable. It has not been verified.

While Liam (in character as Caleb) says it has not been verified, Matt and Laura would later confirm this on Talks Machina discussing the events of episode 34 (video has been made private for reasons that need not be discussed):

BRIAN: When coming up with this iteration of Jester, you modified some of her tiefling racial traits. Did you intend for these to be tied to jesters father when making Jester [...]?
[...]
LAURA: Before I had decided on Jester, I had thought about making a water genasi character. And, I was thinking of doing a water genasi warlock. Maybe she's got some of that in there and she just doesn't know it or something.
MATT: We were at your house working on the specifics of Jester, and you were like "well is there like a possible crossover between the two bloodlines", and I was like "sure, it would change and adjust things a little bit." Skin tone would make sense, resistance wise, I like to think that it wouldn't be one or the other, it would kind of go in a different direction based on that shift. And so that's why she has cold resistance over fire resistance. [...] And the fact that when you do Hellish Rebuke it's cold damage as opposed to fire damage. So it's all just kind of this unique merging of those two bloodlines.

Lillith had albinism.

Kit Buss, Lillith's player, stated in her answer that Lillith had albinism. This was confirmed on stream by Matthew Mercer in episode 91 of campaign 1, "Vox Machina Go to Hell" at around the 1:50:11 mark (youtube link, episode transcript):

MATT: You have encountered an albino tiefling before.

TALIESIN: We have.

MARISHA: Have we?

LIAM: Smartypants.

TALIESIN: Lillith.

LAURA: Lillith was an albino?

MARISHA: Lillith.

LAURA: That’s why she was so pale.

MARISHA: She was so cute!

Answer 4

It is not known

I don't know if there is any in-universe explanation in the show but I found something in the Explorer's Guide to Wildemount's section on tieflings (emphasis mine):

Exandrian tieflings have a wide array of skin tones, all of them vibrant and colorful. The most common hue is a deep crimson, but shades of purple, blue, green, and even yellow and pink have been seen throughout the world. It’s not known what causes these variations, as even tiefling parents with the same skin tone can have children of wildly different colors.

So it is not inherited and there is no further explanation where the color originates from. But at least this part states that there are blue-colored tieflings in this world.

There is also a part in the Player's Handbook and Basic Rules about tieflings, but it also just states the different color variations and does not explain where they come from:

Their skin tones cover the full range of human coloration, but also include various shades of red.

Answer 5

There is a precedent for blue, and a stretch for white, neither with lore explanations

Sword Coast Adventurer's Guide (p. 118) mentions a variant of tiefling with dark blue-tinted skin:

Rather than having the physical characteristics described in the Player's Handbook, choose 1d4+1 following features: small horns; fangs or sharp teeth; a forked tongue; catlike eyes; six fingers on each hand; goatlike legs; cloven hoofs; a forked tail; leathery or scaly skin; red or dark blue skin; cast no shadow or reflection; exude a smell of brimstone.

But that seems to be the only 5e material that mentions a different skin color for tieflings and no direct connection between their appearance and any in-universe explanation, though some parallels can be drawn between tiefling features and certain D&D creatures.

SCAG explains Jester's blue color, but Lilith's is a bit more complicated. According to the 5e Player's Handbook's section on tieflings (p. 42):

[Tiefling] skin tones cover the full range of human coloration, [...]

Which, in theory, can cover an extreme case of paleness, but a pure white Tiefling has no official precedent I know of. However, SCAG also mentions the Imaskari, a human variant with white, smooth skin, setting a precedent as part of the full range of human coloration.
