In my attempts to further my knowledge, and the discussion on old plots, I bring up Roscolene. From what I have been able to gather, it was the dominant gel of its day. What I find most intersting was that Roscolene had colors that are not included in the Roscolux line. What were some of the more popular colors that have "died". Rosco shows on its website that it still offers Roscolene, and it is an 800 series, but somehow I feel that its a different product under the same name. I'm going to continue my search to find one on my own, but might there anyone out there that has an old Roscolene swatchbook they would be willing to part with to allow this student of light to visualize the colors of the past?
