colorful listings

["Johannes Hüsing" <hannes@ruhrau.de>]

Greetings,

unfortunately I cannot assign personal color palettes to my 
program listings. The following document, after processing, shows a
colorful palet, then, unexpectedly, a B+W listing, then another
colorful palet, and a colorful listing. What is wrong in the
assignment of an own palet here?

Best


Johannes
