Yellow lines appear green, but only in Acrobate Reader Hi,I have a very strange problem. Our Software, ELCAD, can output drawings as PDF.When I draw a rectangle in yellow, RGB FF FF 00, it appears green, but ONLY in Acrobate reader.All other tools I tested (Irfanview, Thunderbird, Foxit, Firefox, Chrome and so on) display the PDF correctly.AS our customer inists on using Acrobate, I have to find a solution.In the umcompressed pdf (attached) I found the colour informationstream1 J1 j1.000 1.000 0.000 rg1.000 1.000 0.000 RGThis seems to be correct.If I change all appearances to0.000 1.000 0.000the rectangle has the same green colour in all tools including Acrobate.So only yellow is a problem, but why?Can anyone help me?Thanks in advance,BrChristian
