In each episode Assane wears an orange piece of clothing. For example a hat or a shirt. Apart from that a lot of other orange items can be spotted in the background throughout the series. This matches the colour of the opening credits.
Like his character on the show, star Omar Sy's father came from Senegal.
Arsène Lupin is a character created by French novelist and short story writer, Maurice Leblanc, in 1905.
In almost every Episode, Assane or someone who works with him wears the colour orange, or it is featured in their environment.
Most noticeable in Chapter 7, when Lupin is sat in his lair watching the world and plotting his next steps, he sits in an unusual large black chair. When viewed from behind, the chair is a black mask.
