I've been studying color philosophies. Purelakers are actually green, despite the fact that they live in a sea.

What did this replace in green, out of curiosity?

Also, I've always thought that massive sea monsters are green in philosophy despite living in a sea, but the color pie says otherwise (and I'm generally inclined to follow it). Thoughts?

Shin Herdsman, another vanilla. I will add said card to WoR in a few.

The difference, I think, is that krakens and leviathans aren't really sentient, so they tend to absorb the color of their surroundings. Humans on the other hand, are capable of higher thought, and obtaining a different color identity through their actions, thoughts, and personality.
