White
The white-colored blade symbolizes mist and is used by one of the most talented swordsmen in the series, Muichiro Tokito. He is the Mist Hashira, and his breathing technique was derived from the Wind Breathing style.
This sword blends perfectly with the mist, making it easy to obscure his opponents during fights.
Pink
The pink-colored blade belongs to the Love Hashira. Pink symbolizes love, and it complements Mitsuri Kanroji’s character.
She always appreciates people and is exceptionally kind. The demon hunter is ridiculously strong due to her muscle composition, as it’s eight times denser than a regular human being.
Grey
The grey-colored blade belongs to Gyomei Himejima, and it symbolizes stone. Given his movements, Gyomei’s weapon needs to be extremely strong and sturdy, just like the user and his fighting style.
Indigo Grey
The indigo grey-colored blade belongs to Inosuke Hashibira, and it symbolizes beasts. This blade is slightly unrefined and rugged, much like the user and his movements while fighting.
Yellow
The yellow blade in Demon Slayer belongs to Zenitsu Agatsuma, which symbolizes lightning. The blade’s color and design are sharp and have elements that suggest fast movements.
Zenitsu is one of the fastest demon hunters in the series.
Red
The red blade belonged to Kyojuro Rengoku, and it symbolized fire. The blade’s color represented the user’s unbreakable will.
Kyojuro died protecting his comrades, and he refused to let anyone get injured in the process.
Blue
The blue-colored blade belongs to Giyu Tomioka, and it symbolizes water. His fighting style is quite fluid and powerful, just like water.
Lavender
The lavender nichirin blade belongs to Obanai Iguro, and it symbolizes snakes. His movements require incredibly high levels of flexibility and power.
Bright Red
The bright red nichirin blade resulted from increasing the temperature of the sword that caused cellular-level damage to demons. This can only be done by those with a Demon Slayer Mark.
Black
The black nichirin blade is considered ominous. Not much was learned about this sword since those members of the Demon Slayer Corps died quite early.
Tanjiro Kamado has a black nichirin blade in the series.
