Thank you! When it comes to the colors, I tried to make them a bit clearer but then the symbols became harder to read. With a bit more time I could have figured something out to make it work better, I think. There is however also the COLORBLIND assist option which adds letters to the symbols indicating the type.
Glad you had fun making the masks! I hoped people would play around and make the most goofy or aesthetically pleasing masks. After all it's a bit subjective what feature feels like something or other, isn't it?
