As I understand it, color prints in the 19th century were incredibly hard to make as they worked by taking three shots via RGB filters and then carefully depositing dye for each color in the printing process and it could take days to get it right, and even then it basically needed manual touchups while you made it making it partly a painting. What they could do easily is print three positive slides which could then be projected on top of each other using colored lights.
Of course now you can composite the original negatives easily which is why we now have incredible color photographs of 1900-1910s Tsarist Russia that put to shame ones made with actual color stock 40 years later.
