Yes, see below. Disclamer: it is my first experience in Mac OS X
programming, and I did not care to release resources.

Use:

1) $ ./PdfHelloWorldEffects

File "hello.pdf" contains "hello", font Times-roman, blue color.

2) $ ./PdfHelloWorldEffects punknova-regular.otf

Font "punknova-regular.otf", blue color

3) $ ./PdfHelloWorldEffects
punknova-regular.otf /System/Library/Filters/Black \ \&\ White.qfilter 

Font "punknova-regular.otf", black color due to application of Quartz
Filter "Black & White".
