A blue lightsaber would make sense for Cal, as it's supposed to represent righteousness and bravery, which are traits Cal demonstrates consistently throughout his story.
Since the game itself is canon, fans have to speculate on Cal Kestis' canon lightsaber color — but by all accounts, the answer is blue. The cut scenes and promotional materials show him with a blue lightsaber, as does other merchandise, like the Black Series action figures.
The white lightsaber color in Star Wars Jedi: Survivor could have an implicit meaning that foreshadows Cal's fate in the upcoming games. While the color is merely an option for players, this coincidence also seems to point to where the hero is headed in the future.
The crafting process essentially purified the kyber crystals, turning them into a color that befitted her status as an autonomous individual. This is how Ahsoka Tano's lightsaber was born and what the white lightsaber represents—a force for good, but free of the burdens and restrictions of bureaucracy.
Crystals don't really change color on the regular. Crystals are living entities. They turn red because someone "bleeds them." Simply put, they literally TORTURE the poor crystal until it "bleeds" and is red.

What is the rarest lightsaber color?
Black lightsabers are extremely rare in the Star Wars universe, and only a few have been seen on screen. These lightsabers are typically associated with the Dark Side of the Force and wielded by Sith or Dark Jedi. The most well-known black lightsaber is the Darksaber, which was created by the first Mandalorian Jedi.
Cal Kestis' second lightsaber first appeared in the 2019 video game Star Wars Jedi: Fallen Order. Although the canon color of the weapon's blade is blue, its kyber crystal can be customized with the other possible colors of green, orange, purple, yellow, indigo, cyan, and magenta.
Red lightsabers are the weakest, according to a Star Wars study conducted at the University of Leicester regarding lightsaber colors. Decades of Star Wars lore has dictated that the red lightsabers favored by The Sith offered greater offensive capabilities than the softer colors favored by The Jedi.
A black lightsaber is considered one of the most rare colors in Star Wars. It may now be the most sought after with The Clone Wars, Rebels, and The Mandalorian focusing heavily on the only one known to the canon.
The black lightsaber, or Darksaber to give it its proper name, is one of the rarest lightsabers in Star Wars canon. Despite its rarity in canon, anyone who has seen the second season of The Mandalorian is likely to be familiar with the Darksaber.
Despite the similarities, Cal Kestis really isn't a Gray Jedi in Star Wars Jedi: Survivor. He still represents the Jedi Order and upholds its values. It's possible that a sequel could elaborate on Cal's character to label him a Gray Jedi definitively.
Although Respawn Entertainment hasn't provided a definitive answer, Cal's canon lightsaber is most likely the traditional blue. The promotional art and trailers for both Jedi: Fallen Order and Jedi: Survivor shows Cal wielding a blue lightsaber, despite players being able to change the color very early on in each game.
He beat a fallen jedi and a gen'dai from the high republic era. He cuts through waves of enemies that could overwhelm even powerful jedi masters through sheer numbers. He even has a night sister girlfriend he can combine force powers with.
I stay with classic blue. It suits well to Cal. I mean it's like Anakin with his blue lightsaber, when he became a Darth Vader. Cal also embraces the darkness, just like Anakin.
How old is Cal Kestis in Ahsoka? He looks about 12-14 during Order 66, Fallen Order takes place 5 years later. So about 17-19. Sequel trilogy begins at 34 aby, so Cal would be around his mid fifties in the sequel trilogy, Ahsoka would be a little older, more like late 50's early 60's.
The weakest and most harmless type of lightsaber is the one that has been “baby-proofed”: the training lightsabers. As the name implies, this type of lightsaber is only utilized in the context of training very young Jedi to one day become Jedi Masters.
Kathracite crystals were the weakest of the Adegan crystrals and often used to create training lightsabers for the younglings who were apart of the Jedi Order. They produced a weak pale green blade which produced very little heat and was impossible to inflict wounds.
It appears rarely in the Star Wars universe—so rarely, in fact, that the current canon recognizes only one carrier of a white lightsaber. Ahsoka Tano, the former Jedi Padawan who aided in the rebellion against the Galactic Empire, is acknowledged as the sole possessor of the white lightsaber.
Leia Organa's lightsaber was a blue-bladed lightsaber powered by a kyber crystal in the core of the hilt. It was silver and copper in color and featured mother-of-pearl inlays. Organa's weapon was considered a work of art, having an elegant symmetry with silver and gold hues that evoke to her upbringing on Alderaan.
Luke Skywalker's lightsaber was originally pink in the original Star Wars comics. Obi-Wan Kenobi and Darth Vader both used pink lightsabers in their war against each other. Pink lightsabers have a greater frequency in comparison to the other common colors of lightsabers, making them more powerful.
White - purity, peace, positivity, neutrality. Black - power, darkness, aggression, mystery - The Darksaber is a unique weapon and the only known lightsaber to have this color.
Cal's tattoo is never talked about during Fallen Order, so we don't have a definitive answer as to what it's supposed to represent, but it's been speculated that it's an identification tattoo given to Bracca workers. Concept art for Fallen Order also refers to it as a "company tattoo", which supports that theory.
Edit: so from what I can gather through the comments, he wore a glove on one hand during his scrapper life as apart of his job, like for handling more dangerous things. But after that he kept it on as to prevent his echo ability from constantly giving him the history of things he touches.
Sadly, the end of Star Wars Jedi: Survivor did set up Cal's eventual turn to the dark side. While on the hunt for Bode Akuna after his betrayal on Jedha, Cal loses control and taps into the dark side.
