- I have difficulty distinguishing between green and red, and between gray and pink.
- I think I’m blood type B, but I’m not sure (vague memory).
A personal experience that troubled me:
(Just a personal matter) I wish AtCoder would change the color of the brown and green rankings. As someone with color vision deficiency, it’s difficult for me to distinguish between brown and green in the ranking table.
It seems that there is a senior who wrote an overseas college entrance essay using this as a topic (MIT).
