OP have you considered doing a version for this to test contemporary Greek native speakers, vs others ("control" group),

for differentiation of blues?

I remember reading that modern Greek has two color-names for sky- and dark- blue (not sure what the prototypes are for each nor if they have hue components, maybe the "sky" blue is green-shifted?)... always been fascinated by the discussion of "weak Sapir-Whorf" around this and would be quite interested to see if there are any differences in discrimination...

The classic cognitive/perceptual psyche data to gather would be time-to-discriminate, with the prediction being that Greek speakers make faster judgement because they have higher/faster discrimination, than others.

Not sure how you'd pose the question to non-Greek speakers tho :)
