The word play here is one of nuanced diction here. Namely the secondary meaning of the word:
Meaning 2: recognition and understanding of the difference between one thing and another.
"discrimination between right and wrong"
2a)
the ability to judge what is of high quality; good judgement or taste.
"those who could afford to buy showed little taste or discrimination"
I.e. the true ability to distinguish things, not simply sorting objects by color.
