So, what colour should the Developer C be? Yellow, Purple, Orange or Red? Mine was yellow and I didn't notice anything bad on my negs other than Portra 400 (new) and Ektar 100 coming out a bit pinkish (colour went back to orange after drying).

My working solution now changed colour to green-black after 3 films and the bleacher is full red. Are these normal? Haven't used another c-41 developer before, only done b&w's.
