G, B, Y, M will become white and overlapping with the cyan C to form a color overlaps red. So red R and cyan C I will say that there is a complementary color of relationship. Complementary color of similarly green G is magenta M, complementary color of blue B you can see that it is yellow. Please remember firmly this thing.
