Assuming that Alain is seeing the same thing I see using OS X 10.6.2 and compiling with pdflatex any viewer that uses PDFKit (TeXShop's viewer, Preview, Safari, Skim) shows the shading incorrectly while Adobe Reader and TeXworks viewer show it correctly. If you compile the same file using latex->dvips->ps2pdf all viewers show the file correctly.
I've tried this with MacTeX(TeX Live)-2008 and -2009 with the same result. Ross Moore is using 10.4.11 and isn't seeing the problem. I haven't seen reports on 10.5.8 yet but it appears to be system dependent so I'm assuming that PDFKit has a problem under OS X 10.6.2.
