Could you elaborate on what it is about that observation that is "really interesting"? It is a fun detail, but does it actually mean anything for usefulness or progress or anything really beyond "gpt-6 makes darker colors"?

Not trying to dismiss your work, to the contrary. I'm wondering if I'm mising a deeper insight here.

It shows that the three 5.6 models are closely enough related that they exhibit similar "taste" in their color choices, and the same is true for the 6 models.
