pourquoi tu as besoin de passer par UIColor? pourquoi pas une simple struct?

par curiosité, cette formule elle vient d'où? c'est intéressant de mettre en commentaire la source de l'explication scientifique/mathématiques du calcul

j'ai un "petit" soucis avec ça : c'est que si tu mets + de 2 couleurs, tu pars du principe qu'elles sont toutes équidistante les unes des autres.
dans Illustrator, tu peux faire varier la distance entre 2 couleurs.
dans notre cas ça peut être très pratique pour "accélérer/raccourcir" les zones dans lesquelles les variations sont faibles (ou faiblement perçues) et "ralentir/allonger" des zones où la variation est plus importante

une manière simple est d'avoir un autre init qui te permet d'associer couleur et position
