Is there any difference in hulls between STS Green and Nitro Gold?

This is from a reloading perspective. I can't glean much from Remington's site apart from the Nitro's are loaded a tad hotter.

Is the color the only other diff?

According to Lyman #4, no difference, data is the same for both. I've seen no difference in the reloads.
