[reportlab-users] Reportlab and colors in Adobe Reader

I am using ReportLab 2.4 for a month or so and I am VERY grateful for
this great tool which helps me automate doing large reports!

But I am stuck with an issue of colors. Appending a certain PNG Image
(generated by matplotlib) to the story changes colors. Affected are
colors in images, raw canvas drawings and text. I dont think it is a
ReportLab problem because Foxit and in Evince don't give me this kind
of color mixup. It looks like some kind of RGB/CMYK conversion thing.

I don't want to abuse this list for Adobe screw-ups, I would just
appreciate some assistance from the PDF experts. Here is a sample
document which displays colors on page 3 differently than on pages 1
and 2. Does anybody else see this same problem?

Does anybody know how to get Adobe's attention to investigate this
kind of problem?

Thank you in advance for any assistance,
