[NTG-context] PDF Transparency and ConTeXt

Hi, I have written up a question on TeX.SE: http://tex.stackexchange.com/questions/135543/pdf-colour-space-and-context Aditya mentioned that the problem with transparencies is that it is likely a known bug with Adobe Acrobat Reader: "I remember similar questions being asked in the past, and the conclusion was that it was a known bug in Adobe Reader." Has anyone else come across this issue and found a way to resolve it in ConTeXt? I ran into what I think is a similar issue with LaTeX and was able to resolve it using the following command in the preamble: \pdfpageattr{/Group << /S /Transparency /I true /CS /DeviceRGB>>} I have not yet tried to reproduce the problem in either LuaLaTeX or LaTeX. Kindest regards.
