CD4 is one of the most active color developing agents available. That is one key factor. The other is the relatively low contrast compared to reversal color films.

DO NOT PROCESS C$Q FILMS AT ANY TEMPERATURE OTHER THAN 100 F. I have said this over and over. It is diffusion controlled and goes awry quite quickly with crossover, color shift sand etc.. if mishandled.

Use a 100F prewet and then use a stop if needed.
