Maybe I'm color blind but I disagree, but that's why it would help to look at a side by side picture of the same exact thing with some color in it.
I took my side-by-side photo comparisons, where it is clearly obvious which one is the RCCB, and then I took the blue tarp, and over imposed it on his pictures, and took the street sign and over imposed that on my pictures.
When I do that, I can see how the yellow sign looks like the yellow on my left picture, and not like the yellow on my right picture.
Same with the tarp. The good blue tarp to me looks like the blue sky in the left picture. And the tarp that looks greenish from the RCCC camera looks more like the sky on the right picture.
If you can, take some screenshots of the same exact thing, turned the car around, so that you can compare the same image.
