La palette comporte un bloc de mélange de couleurs. Le procédé de mélange de couleurs comprend les étapes qui consistent : à acquérir une seconde couleur sélectionnée par un utilisateur (S11) ; et, lorsque le bloc de mélange se déplace dans une direction positive depuis une première position de la palette jusqu'à une seconde position de la palette, à mélanger, en fonction d'un incrément de position du déplacement du bloc de mélange, une première couleur et la seconde couleur pour obtenir une couleur correspondant à la seconde position, la première couleur étant une couleur qui correspond à la première position (S12). La présente invention acquiert, grâce au déplacement du bloc de mélange pour mélanger la première et la seconde couleur, une couleur entre les deux.
