Iron Ore vs Poseidon

Iron Ore runs neutral while Poseidon is decidedly cool, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 32.0, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.

Digital color is approximate.
