There was another thread in this forum from a few years ago but it was never answered or resolved - the Roscolux R368 Winkler Blue gel seems to be missing from the color picker in EOS (18.104.22.168). I've looked in all Rosco pages including "Other." Just wondering if there's a way for this one to be added - thanks!
Eos currently does not have a proper calibration for that Gel color, which is why it's not shown. It can be added as a gel on a string.
We will work on getting this added in a future release.
