Add accessible symbol/icon for nitwit villager outfits

As someone with a color deficiency, it is extremely difficult (impossible, really) to tell when a villager is a nitwit or not. Adding a symbol, high-contrast pattern, or similar feature to their outfit would be far more helpful than having to rely on recognizing a color to identify them as nitwits. This accessibility feature would make the game far more enjoyable for those with color deficiencies. Being unable to distinguish the green cloak on nitwit villagers affects gameplay when I try to avoid or interact with them.
