I learned that Ralph Gibson was using Grade 5 and 6 Brovira at his prints. That paper lost. I quickly thinked may be there was a computer simulation for that paper and this question carried me to the next question.
Is it possible to do what computer do with chemistry ? May be I can buy an Ilford paper , mix the simulating developer and woala I got Brovira ! Or may be color filters or whatever I dont know ?
