It was actually quite shocking how much more sense most color choices in art and design made to me, which was a much bigger reason for me to keep wearing the glasses than being able to distinguish red, green and brown better than before. The world just looks "more balanced" color-wise with them.
While it was very obvious early on in my life that I experienced most green, red and brown colors as ambiguously the same (I did not know peanut butter was not green until my early thirties), the fact that there also were differences in perceptual brightness had stayed completely under the radar.
¹ And yes, these lenses do work, at least for me. They're not as scummy as enchroma or other colorblind-"correcting" lenses, for starters you can only buy them after trying them out in person with an optometrist, who tests which type of correction you need at which strength. Ironically their website is a broken mess that looks untrustworthy[0]. And their list of scientific publications doesn't even show up on Google Scholar, so they probably have near-zero citations[1]. But the lenses work great for me.)
