Tilman Hausherr commented on PDFBOX-5970:
-----------------------------------------
I think that what you mean is this: the CMYK colors are [0 0 0 1], but the RGB
colors are [0.08917373, 0.08673228, 0.08380255]. I tried our old CMYK ICC
profile (USWebCoatedSWOP), there we get [0.13707179, 0.12234684, 0.12568857].
I also asked ChatGPT:

> In pdfbox 2, if i set a breakpoint on PageDrawer:
> protected Paint getPaint(PDColor color) throws IOException
> And call org.apache.pdfbox.tools.PDFToImage
> I see cmyk black text is converted to RGB, i expect result should be

> float[] components = color.getComponents();
> return new Color(new DeviceCMYKColorSpace(), components, 1);
