So when I'm running games, it's really hard for me to distinguish when someone is using a torch and when someone is using darkvision. This is important to me as perception checks will differ depending on the type of sight (light vs darkvision) being employed in an area. There are also niche cases where someone using darkvision won't see something where someone using light will. So if light and darkvision would behave differently on tokens that would be great.
