Based on the character 城之内克也 (Katsuya Jonouchi) from the anime series 遊☆戯☆王 (Yu-Gi-Oh!), I’ve created a color palette that reflects his personality and style, which often includes bold colors and a sense of determination.

                         - A clean white that signifies hope and purity, contrasting with the darker elements of his character.
5. Grey -

This palette captures the essence of Katsuya Jonouchi’s character through vibrant and bold colors that mirror his personality traits.
