Are you reading the inside contents of a PDF, seeing something like /ColorSpace 47 0 R? Or something diffferent?

[doxdici]

Yes I am reading the inside content, exactly /ColorSpace 47 0 R or sometimes /ColorSpace 48 0 R

Read about indirect objects in the PDF Reference. These are not colour spaces, but references to them.

[doxdici]

yes, i thought it was a reference in another part of the pdf, but in the pdf there is no object with that number

It might be in a compressed stream. Not all objects are visible in text editors. Suggest you use an app.
