By pausing collide over and over, I have found that while some godteir troll’s shoes are their blood colour, there are some exceptions. Such as: pyropes-red, nitrams-yellow, captors-purple/dark violet, and Kanaya-white. Also, while everyone is in a neutral position, Nepetas have their claws out, and Meulins are in fighting stance.

Yep! Some of the colors are thematic rather than based on their blood color. It’s likely Meulin’s sprites are in a fighting stance because their sprite is based off of Nepeta’s but without the claws? Not sure, haven’t seen them.
