Replicating something verbatim is not my interest. The Lumieres chose what they did because it produced the best result for the time and because it could be manufactured affordably. I think the goal should be a result, not a process. An end, not the means.
Reagent grade, analytical quality dyes from Sigma-Aldrich are always going to be expensive, but there are cheaper manufacturers out there for all sorts of colorants.
