In this commentary, three methods of colour based assessment were used to interpret the pH of five unknown solutions. The authors (undergraduate/graduate students and faculty) consist of one of each major CVD type: protanopia, deuteranopia, and tritanopia as well as one with trichromatic vision. We hope that by presenting the authors' perspectives, we will be able to provide meaningful commentary on the qualitative colour-based practices taking place in higher education laboratories and beyond. taken by the authors using a Samsung Galaxy 8 camera under lighting from a Neewer Ring Light (14 inch, 36W, 5500K LED). Image filtering was applied to the images using ChromaticVision Simulator 9 to simulate protanopic, deuteranopic, and tritanopic vision.
