The average brightness values of those are both middle of the road grey. Sorry I should have rephrased as I misspoke calling it beige but the point still stands that has the most average toned color.
If you look they are middling around 50-60% where as a similar red photo intake would likely have a higher contrast and an average color with a higher brightness.
I’d expect that many images are going to be somewhere near 50% grey if you average their luminance out overall. That’s just the average of every colour though. The fact that averaging a range of things tends toward a standard distribution isn’t particularly surprising. Again though, it’s not hard to get a diffusion model to generate something outside of that expectation.
