This is a standard Ishihara color plate test. It is effective in detecting red-green shifts and deficiencies. The (rare) blue spectrum shift, less so. It has a helpful description at the bottom of each slide. You may have to Google the diagnostic term, probably so you don't have a book to read at the end of each slide.

It is not what I expected. You must trace your answers and know medical terminology. It does not have clear instruction for the user.

We define someone is colorblind after testing with all plates of Ishihara test. If there are all 38 plates, I'll give 5 stars.
