One of the defining traits of the Sigma is their refusal to be boxed. Colette’s life defied the early 20th century’s neat categories for women. She had scandalous affairs with women (most famously with the trans-masculine Marquise de Belbeuf, known as "Missy"), married three times (the last time to a man 16 years her junior), and navigated bisexuality, financial ruin, and literary reinvention with a serene lack of apology.

Colette Sigma, whose real name is not publicly known, is a French YouTuber and gamer with a passion for all things gaming. Born and raised in France, Colette developed a love for games at a young age, which eventually led her to create her YouTube channel. With a background in art and design, Colette brings a unique perspective to her gaming content, often focusing on the artistic and narrative aspects of games.

The "Colette Sigma" trend often manifests in fan art, edits, and gameplay montages. These creations emphasize her power on the battlefield, showcasing her ability to take down even the tankiest opponents with ease. A "Sigma Colette" is portrayed as a brawler who doesn't just collect autographs but dominates the arena through sheer skill and precision. These edits often feature slowed-down phonk music and visual effects that highlight her most impressive plays, aligning her with the broader "Sigma" meme culture.
