Throughout the production of a series, a lot goes on behind the scenes in regards to planning and design, which often go through multiple stages before resulting in the final version that is seen on screen. Some concepts and ideas can have an effect on the show and characters, and unexpected occurrences during production can also lead to changes and additions to the plans for the show.
Jaune alludes to Jeanne d'Arc, or Joan of Arc, which follows JNPR's theme of people who dressed themselves as the opposite gender. Joan of Arc dressed herself as a man while in the French army. This allusion has had the following influences on the character and the show:
- His name is similar to that of Joan of Arc.
- In Volume 1, Jaune had a brief story arc spanning "Jaunedice" through "Forever Fall, Pt.2", which referenced Joan of Arc's tale. In this arc, Jaune is bullied and blackmailed by Cardin Winchester, who alludes to Henry Beaufort, who was a Cardinal and the Bishop of Winchester. Henry Beaufort took part in the trial of Joan of Arc, which led to a false conviction, sentencing her to death by immolation.
The emblem Jaune uses is a rainbow, passed down through his father's side of his family. The rainbow emblem appears on a couple of Jaune's possessions:
- On the front of his shield.
- Original battle outfit - on the soles of his shoes, in Volume 1.
At one point, it was stated that Jaune possesses another emblem. His "true symbol", according to Miles Luna, is on his hoodie, hidden under his chestplate. In "The Next Step", the symbol is revealed to be the mascot for Pumpkin Pete's Marshmallow Flakes cereal. This mascot symbol is also seen on his pajamas in "The Shining Beacon, Pt.2", with a clearer view seen in "Breach". However, due to the nature of the emblem, it is believed that Miles was joking with the audience as evidenced by his laughter when he shared this fact, and that the symbol is simply a fashion choice rather than a genuine emblem.
Ein Lee drew a piece of concept art that shows Jaune with two different outfits, each of which has aspects of the final design of his original battle outfit.
The left outfit has him wearing a black short-sleeved hoodie with red, or perhaps red-orange, lining. Overtop this hoodie, he is wearing a pair of shoulder plates and a breastplate. For bottoms, he is wearing jeans with tan chaps over them and a brown belt with a large pouch on either side. Completing his outfit are a pair of black shoes with white soles and a pair of orange gloves that each have a metal plate on the back.
The right outfit has him wearing a dull grayish-tan hoodie with a tan vest over it and a pair of jeans with a hole ripped in the knee of his left leg. He is wearing a pair of crossed brown belts with a couple of brown pouches on his left side. On his feet is a pair of black boots, which appear to have some armor on the toes. On each arm is orange fabric and an elbow pad, and on each hand is a brown glove with a metal plate on the back and another metal plate sticking out onto his wrist.
It appears that both of these outfits were combined to create the final design that he possesses in Volumes 1–3:
- The black hoodie and armor plates from the left.
- The fabric and elbow pads from the right.
- The gloves from the right.
- The belts from the right, although the pouches were moved to his right side.
- The pants from the right.
- The shoes from the left and the boots from the right appear to have been combined to form a different design of boots.
This concept art also displays a difference in physical appearance. In the drawing on the left, Jaune has red eyes, and in the drawing on the right, he has brown eyes.
It appears that a third outfit option was almost drawn, which would have given him a scarf.
In Volume 1, Jaune has the "rainbow" emblem from his shield on the soles of his shoes. In Volume 2, the soles have been changed to no longer include that emblem, and they are labeled "left" and "right". Miles spoke of this change using Jaune's voice to express concern that he could become concussed and forget left and right.
- When trying to come up with Jaune's personality, his voice actor, Miles Luna, performed various voices for Monty Oum. Monty loved the "nerdy" voice, and that became Jaune's voice.
- Jaune was originally going to be named Jean, as in blue jeans, in order to fit the Color Naming Rule. However, Burnie Burns walked in on the writers discussing it and suggested jaundice.
- This may be the inspiration for the names of the Volume 1 episodes "Jaunedice" and "Jaunedice, Pt.2".
- In Vol. 5: Shine, Ein Lee comments on her various contributions to the series. There, she mentions when working with Monty Oum, she was given a brief description of Jaune with no specific design in mind; "a goofy dork with homemade armor."
- Being one of the show's writers, Miles is uncomfortable with the fact some fans consider Jaune to be a "self-insert" of himself, and he is always insecure about featuring the character. Kerry Shawcross has stated that Monty and himself wrote most of Jaune's scenes in the first two volumes, and Miles admitted he prefers to let his partner handle the character.
- After production on Volume 1 was completed, Monty began making new rigs for the character models so that they could be animated more smoothly. He used Jaune to test the new rig and made a video of Jaune dancing in Junior's nightclub.
- In the original Volume 1 Opening storyboard, Jaune is shown staring worriedly at a large building. He is startled by Pyrrha Nikos placing her hand on his shoulder and sees her giving him an assuring look. He is then shown standing proudly with Lie Ren and Pyrrha, before Nora Valkyrie leaps onto his back.
- After Volume 3, Rooster Teeth changed animation software from Poser Pro 2013 to Autodesk Maya. With this change, the animation department also made all new models for RWBY. The Jaune Arc model's eyes were given a slightly different shape, and the newer hair model gives him the same hairstyle but is structured somewhat differently.
- During the montage in "Sparks", Vine Zeki asked Jaune if he ever considered extending his Aura. Since Jaune couldn't do it himself yet, this would have led into the introduction of the Disc Grenade as a substitute during Volume 7. However, the introduction of the Disc Grenades had to be moved to Volume 8 instead.
