Does anyone know a tool that assessed which type of colorblindness you have? The tool here seems great, but when I want to explain to people how I see colors, I don’t know which deficiency to choose.

However, to properly screen for color vision deficiencies requires calibrated spectra. Thus, even a color-calibrated monitor is insufficient, since color calibration assumes that the standard cone response functions are valid, which isn't the case for anomalous trichromats (which encompasses the most common types of colorblindness). This is why screening, such as with the HRR test, is done with plates printed with spectrally-calibrated inks in controlled lightning conditions (again with a known spectrum).
