Hi Tilman,
I think the javadoc method description is wrong forsetNonStrokingColor(float r,
float g, float b).
The method description says:
"Set the non-stroking color in the DeviceRGB color space. Range is 0..255."
The code validates that r, g, b are in the interval [0.0, 1.0].
Cheers, John

You should use the other call with float r, g, b. Divide your values by
255f.
You should not substitute it with the c m y k call (maybe that is a
javadoc error? Make sure you're using the latest version 2.0.25).
CMYK is a different color model than RGB. If you don't know what it
means, then you won't need it 😂. It is used for printing.
https://en.wikipedia.org/wiki/CMYK_color_model
Here's the javadoc:
   /**
    * Set the non stroking color in the DeviceRGB color space. Range
is 0..255.
    *
    * @param r The red value
    * @param g The green value.
    * @param b The blue value.
    * @throws IOException If an IO error occurs while writing to the
stream.
    * @throws IllegalArgumentException If the parameters are invalid.
    * @deprecated use
    * {@link #setNonStrokingColor(float, float, float)
setNonStrokingColor(r/255f, g/255f, b/255f)}
