Here's a comparison I made quickly. Green text on red background. One is the original, the other is with color subsampled by resizing to 50%, then upscaling again.

In the worst case scenario (extreme color contrasts) this is what you lose with stuff like 4:2:0. The picture that originally looked sharp and defined and like true HD now looks more like a good DVD. Despite full luminance resolution.
Now that we have UHD Blu Rays, we can scale them down to 1080p and have full 4:4:4 colors. It doesn't make a difference in most scenes. But it can make a huge difference with some art elements or fine colorful details.
Hence this thread shall stand as my personal advocacy for 4:4:4 encoding of projects wherever the source justifies it. Which includes, of course, 35mm scans.
