When I was young and would play NES, it was usually on an older CRT TV and the NES was connected via the RF connector. So you had the RF interference, and the fine tuning certainly added things because often it had to be adjusted, and then anything with tint, brightness, etc. was adjusted until it looked good in the room. Some problematic TVs had bleeding colors, etc. or brightness issues, or the antenna connector was broken, causing fuzziness, etc. Take the analog path from NES to TV in that common situation, then the second analog path inside the TV generating the color, then NTSC color/lum separation limitations, and "crisp" or "accurate" is something that couldn't describe the results. On nesdev.com there's at least one thread where quite a few people are discussing about the best way to capture the color palette from video sources, and argument that there really isn't a "golden palette" because each TV was different and NTSC quirks: a pixel sent to a CRT TV could have different colors depending on its position and the colors/luminance before and after. So CRT/NTSC fuzziness is part of the memory and nostalgia. I like the NTSC emulation options in FCEUX which do a really good job of the color fringing and smearing that was on CRT TVs and really make it "look" like how it was when I was young.
