No, no! Use 2/3 the weight of pyrogallol in place of the catechol. So, instead of 100 grams of catechol use 67 grams of pyrogallol. Metol and pyrogallol are the only developing agents, not counting the small amount of ascorbic acid.
So, 133 gr. of Pyrocat instead of 100 gr. of pyrogallol will do well too?
