What is heterochromia? Well, that's what I'll be talking about in today's blog post! This is something that's somewhat common to see in anime, since it's a good way to make a character stand out. Heterochromia is when each eye is a different color. It's a real condition, but you'll see it much more often in anime than you will in real life. Characters with different colored eyes are usually very popular, since it's a popular design choice. It's a good way to make a character look unique, so many artists like to give their characters these eyes. As always, here's a picture of Obanai Iguro from Demon Slayer as an example. Enjoy!
