If you could show a basic level of consistency. Take the correctly rendered title on the book vs the incorrect colors; the odds that it got lucky with the text instead of a different title or a book with random letters on the cover are negligible. But if your evidence revolved around the color of the book the villain stole from the library, not so much.

So if you're planning to do crime, make choices where the evidence relies on spectra rather than geometry. Steal Rothkos rather than Mondrians; baggy coveralls are in, form-fitting ninja wear is out.
