That's interesting. When I compiled it with "java kawa.repl -C  
chameneosredux.scm" it worked for me.

$ javap chameneosredux | grep "public static void"
    public static void main(java.lang.String[]);
    public static void printAllColors();
    public static void printColors(Color, Color);

I didn't try compiling with --main, though. Your changes probably make  
the program more Scheme-ish anyway.

Yeah. When there's a better way to iterate over an array, too. Which  
reminds me, a while back I wrote map and for-each functions which  
worked on arrays and java.util.Collection instances (attached). They  
may be of general interest.
