Good use of colour here.
They break the “rule” of only using one colour, but by allying ‘Excedrin’ with ‘Effectiveness’ and ‘Tylenol’ with ‘Gentle’, they make the extra hue worth it. Hue comes to represent both the quality and the exemplar of the quality. Also, the multiple colours clarify the transition between slides.
I also like the liberal use of mathematics.
Perhaps “perception” is not a dimension, isn’t isomorphic to ℝ², or is unrigorous for many reasons. No matter. Math is a language, a way of thinking, and in this case it’s the clearest way to make the point.
