Hue.

A blue-skinned character with red hair and a red cape looks down with a hand raised, then turns their head slightly. A character with brown hair and a blue and purple striped shirt stands with their back to the viewer, looking at a reflection in water. A character with red hair, black and white clothing, and glowing green eyes lunges forward with a glowing sword. A character with dark hair is shown in a close-up with a white face and a wide smile. The scenes take place in a dark, purple-lit environment.
