Maria is the daughter of Lavender Wyrzykowski and Michal Wyrzykowski. She is an only child, born in Halifax.
Maria has always been artistically inclined, drawing and painting from a very young age, so by the time she reaches high school, her parents enroll her at Hartley's Academy for the Arts so she can study art further there. On her first day of grade twelve, Maria is attacked by a mysterious person who appears at the school. She is approached by the Spirit Hue, who grants her the ability to transform into Cure Palette and thwart the attack.
Soon after, Maria is joined by Elise Bellerose and Ana Bauer, who are also granted Pretty Cure powers by their respective Spirits of the Arts, and they form a team to protect their school from the ongoing attacks seeking to snuff out their creativity.
By 2046, Maria is 47 years old, and is raising a daughter, Amy, who has just begun attending a culinary school. She soon learns that her daughter and her girlfriends Isabella and Mei have also become Pretty Cure, and transforms once more to assist them in battle. A few years later, Maria and her daughter transform alongside her mother, aunt and cousin to aid her cousin Cure Swallowtail and her partner Cure Monarch in battle.
As Cure Palette, Maria gains powers based on painting and becomes the Pretty Cure of Painting. Maria transforms via the charm that Hue transforms into for this purpose. While transformed as Cure Palette, Maria has heightened physical abilities, able to withstand great force, as well as launch herself through the air at great heights and speeds.
Cure Palette's primary attack is Pretty Cure Rainbow Technique. In order to perform this attack, Palette summons her Magic Brush from Hue, and waves it through the air in the direction of the target, then blasts paint at them, which becomes magical energy that purifies evil.
Elise Bellerose - Elise was one of Maria's first friends at Hartley's, despite their differing disciplines. She thinks the girl is super sweet and supportive and feels she can trust her with anything.
