Description

Foncer ou éclaircir tous les pixels ayant une dominante rouge, bleu ou verte. La dominante d’un pixel est parmi les trois couleurs primaires celle à l’entier le plus grand. Pour foncer (respectivement éclaircir) un pixel, on ajoute (respectivement retranche) un certain entier à chacun des trois entiers la décrivant.

Contributor guide

Research direction
Implement a function that iterates over pixels, identifies the dominant color (the one with the highest integer value), and then darkens or lightens the pixel by adding or subtracting a constant to each channel accordingly.
